This article will describe in detail the information that will allow the most correctly calculated the number of sawn timber in the cubic meter of a wooden board. To date, the edged and unedged board is the most popular sawn timber. Manufacturers produce numerous variations of this material with dimensions from 16 × 8 mm to 250 × 100 mm.

In this case, the width of the board is always at least twice the thickness, if the aspect ratio changes - the material is already called the timber. The cutting board is taken to measure cubic meters, so to determine the cost of the work you need to learn how to determine the weight of the cube edged board. Fortunately, there are ready-made tables and formulas that allow you to quickly cope with this task.

As a rule, most novice builders do not think about the issue of "Cub meter of boards - how much » , but simply use the table below. However, we strongly recommend learn how to calculate the cube yourself, it will greatly simplify the work, and only in this case you can consider yourself a professional.

If you compare the cutting board with an unedged or one-sided-edged, on the surface of the first there are no places where the bark was previously, this parameter is called a review. A small review is usually allowed, but what is less, the better. So in terms of geometry, this board is guaranteed is a rectangular parallelepiped. This figure has three parameters: thickness, width, length that is accepted to express the letters a, b, l. These indicators are enough to know how to calculate the boards of the board in a few seconds.

It is important to know that there is an official standard for which the boards can be produced only with the parameter "A" equal to 22, 25, 30, 40, 50, 100 mm. There are also other sawn timber that are made from other longitudinal planing methods or cut. Their width varies from 100 to 250 mm, step 50 mm. The length of such boards can be 3, 4, 6 m.

Cabinet calculation formula

Thickness * Width * Length

(A * B * L)

Once you have learned all the values, you can quickly answer the question of how to calculate the cube of the board. Before calculating, you need to translate all the values \u200b\u200binto meters. For example, we have a 25 mm x-10 cm x 4 m, when transferring to meters it turns out 0. 025, 0.1, 4. Now we turn these parameters with:

0.025 * 0.1 * 4 = 0.01

Now the unit divide to the result received and learn how to calculate the cube of the boards, or rather the number of boards in a wood cube.

1 / 0.01 = 100

Thus, in the cubic meter there will be 100 boards of the specified sizes. Now you can easily answer the question of how to calculate the boards cube, however, you need to learn to consider the number of lumber required to perform work.

What is a piece of inches and how to calculate her cub

The inch is only the name of one of the size of the boards, there are also forty-fighters, five, brushes, it allows the builder to quickly navigate what board is we talking about. To find out how many inches in Cuba, you need to make calculations already familiar to us, as a result of which it turns out with a 10 cm-66 boards width - 66 pieces, with a width of a board of 15 cm - 44 pieces. As a rule, one cubic meter is enough to cover the area 40 square meters.

As already mentioned, there is also an unedged board, which is obtained as a result of longitudinal sawing logs without processing on the sides. So it is to find an answer to the question how many boards in Cuba Unedged Board are usually somewhat more complicated than in the first case. The fact is that unedged lumber are accurately indicated exceptionally width and length, but the width can vary. Much depends on which part of the tree a certain board is cut. If you are wondering how to count the cab of the board is unous, you need to think about the task set first.

For example, you may need to strip structure, in this case, you first know the finishing area and multiply it on the thickness of the trim, this will calculate the required amount of material. We describe this situation in numbers:

How much can unedged whiteboard thickness 25 mm thick on the rectangular clause 10 * 5 meters and 3 meters high?

Consider the entire area for finishing, for this we produce multiplication of the perimeter of the building at its height: (10 + 10 + 5 + 5) * 3 \u003d 90 square meters. Now the value obtained is multiplied by the thickness of the material: 90 * 0.025 (we translate millimeters to meters) \u003d 2.25 cubic meters.

As you see, in this case, it practically does not matter the width of a separate casing element, since this does not affect the common cub. However, sometimes you can still come in handy the knowledge of the averaged dimensions of the board, which will make it possible to approximate how many unedged boards in Cuba. These approximate data are specified in the table.

Almost everything in our world has its measurement value. Oil measuring in barrels, coal in tons, population of countries in thousands, millions.

As a basis, we take the amount capable of specifically to designate the object that we measure. When the question arises how to calculate the cube of the board, the speech is already not about the mass of the subject, since wood has a completely different density, and one tree has differences from the other. In addition, the boards of the same breed will have a different weight taking into account their humidity.

For the convenience of calculating the board of the board, the volume measurement formulas are used.

It is enough to recall the school mathematics and the necessary formula that should be multiplied by the width, length and height. For the correctness of the calculation, it is necessary to adjust all parameters for one value, for example in centimeters or decimeters. It is most convenient to take a meter base. Thus, making three times multiplication in meters, we get m³ or cube.

Note. Special formulas are used to calculate the boards of the board.

Cubature boards

Boards may have differences in width, length, thickness. In addition, they are implemented by unedged and edged. Often lumber have their own generally accepted standards that facilitate the calculation of the cub.

For the usual sizes of material, there are already calculated volumes that are systematized in the table of measurement of the boards. Therefore, to determine the volume of the material, it is necessary to simply open the table with the designated dimensions and calculate the volume.

But in order to do this, you need to have these tables with you. Otherwise, for the lack of such, the cube of the cutting board is calculated, before determining the thickness and length. These are the main dimensions corresponding to the requirements for lumber. Everyone separately taken is different. For example, a board is used to create a crate, in which the thickness is 25 mm, and for black floors is 50 mm. Next you need to measure the width of the board.

In the case of a edged board, everything is simple because the material is cut into order to give one width. Next, with the help of a calculator, all values \u200b\u200bare multiplied with each other. With the length of the board, 5 m, the thickness of 50 mm and a width of 25 cm, the volume of the material will be:

5 x 0.050 x 0.25 \u003d 0.0625 m³

After multiplying the resulting number on the number of boards, we obtain the volume of the material.

Formula for calculating cabbage boards

V \u003d L x H x B

L - Length

h - Height

b - width

Determination of the number of boards in the cubic meter

1 m 3: v \u003d n

In order to determine the cost of a specific type of board, with known volume values: V x Price 1 m 3.

There is another point to which it is necessary to pay attention to the definition of the boards - the nominal length exactly is 6.1 - 6.2 m, but during sale this is not taken into account. Often it matters in the case of purchasing a large amount of material. For example, take the board with dimensions of 150 x 20 mm.

Having performed simple calculations, we obtain the number of boards in 1 m 3 - 55, 5 pieces. Thus, in the cube of the board 6 m, there are 55 pieces, and in the calculation, we obtain the value of 0.99 m 3. Essentially, the overpayment of the board's cube will be 1% of the exact price. For example, at a cost of 4,995 rubles, we pay 5 500 rubles.

Unedged board

Features of calculation

The calculation of the cabbage of the unedged board is somewhat complicated, since the material does not have one width between different boards, but also in each board separately. This is explained quite simple - the tree does not have the same diameter.

It is clear that at the bottom it is wider, at the top already. Thus, the width of the edged board does not fall under any standards. How to be in this case? Use to calculate with different formulas. The width of the board is measured for convenience in the middle of the length. So you get the average width. This calculation method works well if the batch of material is small.

For industrial volumes

This method is not suitable, since the work will pass very slowly, and this is not profitable. For such cases, experts have developed the so-called cabin boards unedged. The volume in it is obtained by measuring and experimenting, simply speaking, using a plurality of measurements and calculating the average width value.

Of course, it cannot be called a super precise way, but deviations are so insignificant that they should not pay attention to them.

Some enterprises involved in wood processing are used in practice the method of measuring the stack. For this, it is not necessary to pre-sort the wood in width. Experts make the length of the boards, the average width and height of the stack. The obtained values \u200b\u200bare multiplied with each other, and the result is multiplied by the coefficient for calculating the board cube, which has a mean value - 0.67.

Weighing method

In order to measure the cabin of the board is unous, having obtained the maximum possible accurate result, the weighing method is used.

Before doing this, it is necessary to measure the humidity of the material and the dense tree. Considering the fact that the edged board is the cheapest material used at objects with the smallest degree of responsibility, then complex calculations are not too much justified.

Also, it should be considered that the result you get will not be particularly different from the one that can be obtained using a cube.

When erecting residential buildings

Here professionals are obliged to make many tasks, among which: the calculation and compilation of estimates before performing the finishing of the premises. In addition, it is necessary to calculate the required number of building materials. It is worth noting that this task is quite difficult. Considering this, the definition of the boards of the board is an important point.

Note. The cubic meter of sawn timber is calculated using a single method. The boards variety does not affect the result.

To unfolded species Woods include: edged board, unedged board.

Spooned species - These are those who have special grooves for perfect bumps of boards: flooring, lining ,. Please note that purchasing a whipped board, the calculation is carried out using the working width of the material, without spikes.

Regarding the calculation of the cabbage of the unedged board, with the values \u200b\u200bof the width of one end, 25 cm, and 20 cm - the other, the average value will be 22 cm. To calculate a large amount of material, it is unfolded in such a way that the wide part does not have differences from a narrow more than 10 Santimeters.

The main length of the board in an unfolded pack must be approximately the same. Then, using a roulette, measured the height of the stacks from the boards and the width in the middle. The result, which is obtained by measurements, is multiplied by a coefficient with a value of 0.07 - 0.09, which depends on the air gap between the boards.

There is no such construction that would cost without the use of sawn timber.

Therefore, it becomes necessary to determine the exact amount. Calculate how many boards in 1 cube can be using formulas, and you can use ready-made tables. These tables are called cabinets.

We note that it considers products from wood of coniferous rocks.

What is cubature

In general, this is the volume of any body, expressed in cubic measures.

The lumber cube is the volume of lumber, expressed in cubic meters, otherwise - in cubic meters or just in cubes.

Types of sawn timber

In this section, we will tell about lumber in the order, in which they are obtained when the logs are pickled.

Obapol and Gorny.

For some reason, confusion arises with the definition of these materials: someone claims that this is the same, and someone - that Obapol is produced from the porridge.

The proposed table will make a complete clarity.

As can be seen from the table, it does not apply Obapol in construction, so we will not consider it in the future.

The requirements for the hill are normalized in accordance with the OST 13-28-74. And this means that the horn is a full-fledged building material.

The porch is applied:

• for a roughing device;
• roof shabby;
• making formwork.

Unedged board

It is propylene on two opposite surfaces called plastics. The edges remain uncurned, hence the name.

Its standard sizes are as follows: thickness - 25, 40 and 50 mm; Length - 6 m.

The scope is wider than the porch.

Applied also for construction:

• warehouses;
• utility premises;
• temporary fences;
• sheds.

In addition, it can serve as a base under the cladding clapboard, a block house and other finishing materials.

Edged board

It differs from the unedged by the fact that propylene on the plas and edges.

Used as:

• roof shabby;
• crates of walls of frame houses;
• racks and skews of frame houses;
• stairs;
• material for the manufacture of country furniture, etc.

Bar.

It is a lumber thickness from 100 mm and more with the difference in the width and height of the section no more than twice. Typically, the bar has a square cross section. The most used bar has a cross section of 100 × 100 mm and 150 × 150 mm.

Used:

• in the construction of frame houses in the form of racks and beams;
• as a material for outdoor and inland walls of wooden houses;
• for the device of stairs, fences, etc.

Bar

It differs from the bar in the fact that the maximum size of its cross section is 75 mm. Like a bar, most often made with a square cross section.

Used for internal works, such as device:

• stairs;
• railing;
• window sills;
• base for finishing sheat;
• controls of the roof.

How to calculate the number of boards in Cuba

Edged board

As is well known from the course of high school, the volume of rectangular parallelepiped (and the edged board, the timber and the bar is it, it is he who) is equal to the product of its lengths.

Calculated by Formula 1:

where: V is the volume; L - length; B - width; h - height (in our case thickness) board.

Calculating the volume in this way, you can easily find the number of boards in Cuba.

To do this, it is necessary to divide the unit to the resulting number (Formula 2):

where: n - Number of pieces, 1 - 1 cubic meter. M, V - volume.

We should not forget that the dimensions of the edged materials are given in millimeters, so before the calculation they must be translated into meters.

Example

There are sawn timber with the following parameters:

25 × 150 × 6000, where 25 - thickness; 150 - width; 6000 - Length.

Calculate the cube of the board.

To do this, we will translate millimeters into meters and substitute the obtained values \u200b\u200bin Formula 1:

V \u003d 0.025 × 0.15 × 6 \u003d 0,0225

The resulting number to substitute in formula 2:

N \u003d 1 ÷ 0.0225 \u003d 44.4

The result obtained is always rounded up to integer numbers by discarding the decimal part.

Thus, in one Cuba contains 44 whole boards.

Unedged board

Solve the previous task in this case is more complicated.

Unedged big difference in the width on opposite plastides, therefore, when calculating the volume in Formula 1, it is necessary to substitute the average width: these two widths fold and the resulting amount is divided by half.

The measurement result is rounded up to 10 mm, the shadow of up to 5 mm is not taken into account, and the shares of 5 mm are more considered for 10 mm.

In addition, the uncircumcised edges do not allow to lay the board into a dense package, and various increases are used to calculate the exact volume.

The calculation technique is not so complex as tiring, therefore it is easier to use the table from the next section.

Bounded board and lining

They differ from each other only with dimensions, so the calculation method is the same for them.

They are mounted on the "Spool-groove" system, as shown in the figure.

In this case, the so-called "working" or "visible" width is accepted in this case - the distance from the base of the tongue to the edge of the board (see Fig.). It is this size that should be substituted in formula 1.

Tables of the number of boards in Cuba

In order not to calculate the quantity and volume each time, special cube tables were drawn up, in which its number in one cubometer is given for each material size.

4 meter boards

6 meter boards

4 meter bar

6 meter bar

Unedged Material

Due to the large scatter of the size in length, thickness and width, it is impossible to calculate the exact amount of the porridge in one Cuba, so there is no table-cube for it.

Here is the table of recalculation of the rolling volume of the hill in dense.

In this case, we solve the inverse problem: we determine which actual volume has a known amount of porch.

For this you need:

1. Disassemble the porridge on the bore (which is removed the fattest, the nearest to the root of the tree, the end) and the non-corrosive.
2. Sort in length - up to 2 meters and more than 2 meters.
3. If necessary, sort the thickness.
4. Put in the bag, alternating thin and thick ends.
5. Calculate the share of the package.
6. Select the appropriate coefficient from the table and define the actual (dense) volume.

Cubean for unedged board.

Calculation of the area of \u200b\u200bthe coating

When the main construction is completed, it is time to start finishing work: sow walls and flatten clean floors.

To do this, remember the formula 1. Calculating the volume of one element, write the intermediate result - the product:

where S is the area of \u200b\u200bthis element.

Calcuting according to formula 2 quantity, multiply the result on the area.

Lumber suppliers, measured it in cubic meters (M 3) and the price is respectively indicated for 1 m 3. Calculate sawn timber in Cuba (cubature), find out the number of boards, knowing their size will not be difficult with this calculator.

Specify the dimensions of one board or bar in millimeters:

W. - The width of the board or timber, is chosen by you based on the use of lumber. According to GOST 24454-80, lumber width can be from 75 to 275 mm. Select the optimal value of the width should be tailored to the joint venture 64.13330.2011 (updated edition of SNIP II-25-80).

H. - The thickness of the board, the important parameter of the cross section of the material. Thickness, according to the above standard, can be from 16 to 250 mm. Take into account the joint venture 64.13330.2011 "Wooden designs" to establish value H..

The timber is considered a lumber with a thickness and width of 100 mm, attitude H./W. Not less than 1/2.

L. - The length of the board depends on the length of the source logs (i.e., if a 4000 mm long billet is cut, then the board will be the same value). Value L. It may vary from 1000 to 6000 mm.

E. - Quantity in cubic meters - This item must be selected if you want to know how many boards of a certain size will result from a given number of cubic meters of wood.

Also indicate the cost of 1 meter of cubic lumber in your area.

Opening Results Online Calculator Lumber

If you specified the parameter N. (i.e. how many pieces), the calculator will calculate what volume the wood must be cut to obtain a given number of boards. And if the parameter was specified E. (i.e. volume) will be counted how many pieces of boards can be obtained from such a volume of wood. Will also be calculated which volume is one board or timber (with parameters W., H., L. Chosen by you) and how many in one cubic meter pieces of boards (timber) of this size. If you have led the rates in the relevant paragraph, the total cost of sawn timber will be calculated, their volume and quantity. These data will be useful when drawing up estimates.

With a thorough inspection, a certain number of sawn timber can be selected due to defects. Therefore, so that at the final stage of construction did not have to buy the board, it is necessary to make a small stock over the calculated quantity (approximately 10-20%).

The edged board is the most common type of sawn timber. It has an extremely wide range of applications. Its sizes are the most different - from 16 * 8 mm to 250 * 100 mm (but the width is always more twice the thickness; if less, then such a sawn timber is called "timber"). Due to the widespread and popularity of this material, with almost any construction work, the issue of calculating the required amount of boards will rise with a very high probability.

The edged board is an indispensable material in construction. Its necessary amount is measured by cubic meters.

A cutting board is measured, like the remaining lumber, cubic meters. Accordingly, its cube calculation is an important practical task, the solution of which is necessary to determine the cost. It is simple - enough elementary geometric knowledge.

How to calculate cubature

Unlike the unedged or one-sided-edged board, the edged does not have a concern (parts of the former surface of the log, where the bark is present or before). Rather, a small review according to the standard is allowed, but its number is clearly normalized, and in any case it is small. Therefore, in the geometric sense, we have a simple rectangular parallelepiped. Accordingly, we have 3 parameters: thickness (smaller side of the transverse cut), width (big side of the transverse cut) and length. They are traditionally letters a, b and l.

According to current standards, edged boards are produced thick (parameter a) 22, 25, 30, 40, 50 and 100 mm. Lumber of different thicknesses are made from standard longitudinal sawing or planing. Standard width is from 100 to 250 mm in a step of 50 mm. Standard lengths - 3, 4 and 6 m.

To determine the cube, we need in accordance with the formula for calculating the volume of rectangular parallelepiped multiply the thickness, width and length.

All three parameters should be considered in meters: That is, dimensions 25 mm * 10 cm * 4 m should be written as 0.025 m * 0.1 m * 4 m. Thus, we obtain the volume - the cubature - one parameter data board. Now you need to know how many "fit" in one cubic meter. To do this, it is necessary to divide the unit to the calculated volume. All, the sought number is found.

Example: Suppose we need lumber 6 m long, 3 cm thick, and a width of 25 cm. Then the volume of one thing will be 0.03 * 0.25 * 6 m, or 0.045 m³. In 1 m³ will contain 1/0.045 \u003d 22.222, or, rounded, 22.2 of the board of the specified sizes.

Having a similar calculation, it is already possible to estimate further, how many cubic meters of this lumber must be purchased for construction or repair work. It is worth considering only that supplier firms love to round all the numbers in a favorable side for themselves, and in our example 0.045 m³ in practice can turn at 0.05 m³, that is, in just 20 pieces per cubic meter. Such a "error" can reach a few percent that at prices several thousand rubles per cube is already a prominent value.
