The seller and the buyer of timber pursue their interests. In such a rather fine business, we must have defined - simple - knowledge. The tool today has each: the calculator in the phone.

What is a cutting board cubic meter

How many edged board in one Cuba - Photo

Edged board - sawn timber with purely cropped edges, without bark residue. The width of the edged board exceeds the thickness of at least twice.

Since the fee is charged for the volume in cubic meters, we recall the geometric formula of its definition:

W * V * d \u003d volume.

Everyone is considered in meters

To find out how many blackboard in one Cuba:

1 / (W * B * d) \u003d number of boards in 1m3 (Cuba)

where, Sh- width, IN- height, D.- Length

Translation: 1mm \u003d 0.001m, 10mm \u003d 0,01m, 100mm \u003d 0.1m

Below is a table of certain types of edged board and its volume.

When buying lumber in small quantities, you can get confused with decimal signs, namely rounding. An experienced seller received the number rounded to the 3rd sign after the comma. Experienced buyer round GOSTu to 0.000001 cubic meters and remind the seller that up to 0.001 cubic meters. meter rounded only party of boards. The most common amount is from several boards up to 2-4 cubic meters - the party does not constitute. In order not to offend any other, round up to 4 sign after the comma.

Then the resulting volume is multiplied by the cost of 1 m3 (Cuba). And here the number of signs after the comma can significantly affect expenses.

1 edged board with a thickness of 32 mm, 200 mm wide and 6 m long(32x200x6000) Has the volume

• 0,032 * 0.2 * 6 \u003d 0.0384 Cuba

30 boards will have volume

• 0,0384 * 30 \u003d 1,152 cube

If the seller rounds the volume of 1 boards to 0.04 cube, then will additionally receive income:

• 0.04 * 30 \u003d 1.2 cube
• 1.2 - 1,152 \u003d 0.048 Cuba

Sale of these 0.048 "air" cubes facilitates the wallet of the buyer

The cost can vary depending on the variety of wood. Crowded decreases with a decrease in quality: the presence of water vices and deviation from standard sizes. If the floorboard has a curvature, or thinner than the standard for 3-5 mm, it will not be completely in the case. Visual control of sawn timber is as important as the exact definition of volume.

Covered edged board area

To find out how much the sawn timber you can help the calculation of the board in Cuba. The above formula of the basis has the definition of the area

W * d \u003d area.

Calculating the area covered, it remains to multiply it on the required bottle thickness

W * d * 0,022; 0.025; 0.032; 0.04 m and so on.

It remains to see how much the boards in one Cuba, and determine the desired amount. Just in case print or remember the table above.

It is also necessary to take into account the future cutting material.The flooring and trim board "Lining" have a blocking spool, which is taken into account in the cube, but not included in the area covered. A pair of boards is necessary have in reserve .

Determining the volume of the Unedte Board

How many boards unedged in one cubic meter - Photo

Unedged boardThat is, there is no rectangular section along the entire length, substantially cheaper and is widely used for the device of various types of draft doors, temporary fences.

It is important to understand that the upper and lower boost of such a board must be propylene along the entire length. If one is not propylene, then this is already gorn. The definition of the cube of such a lumber is different because it does not have the right geometric shape.

The current standards set several ways to account for the unedged material, and calculate exactly how many boards in 1 cube are practically unable.

1. Batch.
2. Plucous.
3. Method of samples.

In batch The case of the board is tightly fit into the correct form with a further measurement. Further calculation is under the standard formula for determining volume. Using various coefficients.

CUTTING OMDER It is made on averaged height and width measurements. The biggest and smallest dimensions in meters are folded and divided in half.

(SHMAX + SMIN) / 2 * (VAX + VIN) / 2 * d \u003d volume, m3

where, Sh- width, IN- height, D.- Length

If visually can be seen that the wood is fresh and, accordingly, raw (humidity above 20%), then the seller must reduce the total multiplication of the resulting cube on the coefficient:

• 0,96 For coniferous rocks
• 0,95 For deciduous.

Sample method It is used to determine the volume of a large batch of unedged lumber. When loading, for example, in a vehicle body, every fifth, tenth or twentieth board is measured according to the second method.

The resulting volume is multiplied by five, ten, twenty. Loading continues until the next control board. The selection of control boards in a separate foot is also practiced. Counting is performed after the loading is complete.

Calculation of the volume of timber: how many bar in Cuba?

Calculation of the number of timber in one Cuba - Photo

From the edged board, the timber is distinguished only by the fact that all his facets or two opposite have the same size: more than 0.05m in thickness and 0.013m in width. Formula to determine its volume standard

W * T * d \u003d volume of timber, m3.

To find out how many timber in one Cuba

1 / (W * T * D) \u003d number of timber in 1 m3 (Cuba)

where, Sh- width, T.- thickness, D.- Length

Translation: 1mm \u003d 0.001m, 10mm \u003d 0,01m, 100mm \u003d 0.1m

When buying a bar, the volume must be determined by the ply, since the stack of the bar is laid by gaskets. The measurements of such a stack and the calculation of the cubature according to the above formula consistently lead to significant overestimation of volume.

Length 1 Cuba Bruus (as well as any edged lumber) in meters is determined by dividing units on the thickness and width. For example, you need to know how many timber in one Cuba - a face 180 mm.

1 / (0.18 * 0.18) \u003d 30 meters 87 cm.

1 meter of such a bar will have the following volume.

0.18 * 0.18 * 1 \u003d 0.0324 m3.

These calculations may be needed when determining the costs of means and material.

The volume of the construction log: how many logs in one Cuba?

Breeding facilities are and will be relevant. The determination of the volume of the circular material depends on the method of obtaining it.

• Building log handheld ham.
• Building log, rounded on special machines.

The cutting of the trunk for squeezing manually has the form of a slightly truncated cone, therefore the formula of the cylinder volume is used, but with some features.

3.14 * R 2 * L \u003d log volume, m3

Here
r.- averaged radius, calculated as (R 1 + R 2) / 2, R 1 - radius from one end log, R 2 is a radius from another log end.
L.- Length log.
3,14 - Constant "PI".

The rounded log is naturally cylindrical and calculated according to the above formula. But here the radius is measured at any end once. The determination of the number of logs in 1 Cuba is determined similar to Brus.

1 / (3.14 * R 2 * L) \u003d Number of logs in 1m3 (Cuba)

Blots for construction logs are measured by the same way.

The radius (diameter divided by half) is measured without taking into account the thickness of the wood bark. In practice, manual calculations are not carried out. Enjoy special tables reduced to the Book-Cubature. They are in electronic form.

In conclusion, it should be noted that sawn timber for responsible works, standard in size, wood and humidity breeds should be purchased on large sites. A small manufacturer, as a rule, is not allowed there due to the lack of appropriate control over the quality of products.

How to determine the cube (volume) of the material? It is very simple if the material as in our case has straight corners. You need to multiply the width on the thickness and length. And what to find out how much this material in Cuba, you need to divide the resulting result on the cubic / meter. Here is an example of how to determine how much in Cuba boards with dimensions of 50x150x6000mm. We will decide in centimeters.

(Thickness) 5cm x (width) 15cm x (length) 600cm \u003d 45000 cm / cm

Cube is equal \u003d 100cm x 100cm x 100cm \u003d 1000000 cm / cm

(Cubic / meter) 1000000: (board) 45000 \u003d boards in Cuba 22.22 pieces.

If you want to know how many square meters in Cuba Lumber, you need to split the thickness of the board in centimeters per 100 centimeters. Suppose you buy the lining of 12.5mm x 90mm and know that its square meter costs 120 rubles. The decision will be so.

Molding thickness 1.25 cm 100: 1.25 \u003d 80

It follows from this that this lining in Cuba will be 80 square meters. And that the cube of this lining will cost 80x120 \u003d 9600r

When performing the construction of a cottage or home, the master due to necessity performs many different tasks. It thinks over all construction processes, is the necessary estimate for each of them. Calculate correctly the number of necessary materials is not easy. This requires knowledge of mathematics. He must know: how much in 1 Cuba boards, how much and so on. If he owns such knowledge, it is great! He is a real master!

And for the unfair man "how many boards in Cuba" is the concept of distracted. In order for him to understand it, you should know exactly what construction materials are made of wood. What are they, how are they measured? Not knowing this, he will not be able to adapt in these calculations.

Edged or tipped, as well as other types of lumber

The first thing you need to learn is that it is not so important from what forest was made exactly one or another material. Let the boards are not the same, but their calculations will fully coincide. Let them have different varieties, various sizes, the calculation is made anyway along the same principle. It's still wood, and will measure it equally! Can only define how many in 1 Cuba are boards every time it will be different. Regardless of the edged or tipped, cylindown, etc. The calculation will be the same.

Unfolded lumber - Miscellaneous timber, edged materials, not cutting their analogues, is the case when their cube is calculated quite differently! These products have grooves, spikes. They are intended for docking between units of forests among themselves. These products are counted:

• blockchasa;
• floor material;
• imitation of various timber.

When purchasing such a center, the circumstance should be taken into account. When calculating the cube, you need to take only the working width of the bar. Ship here is not taken into account. And when calculating the blockature of blockhause, which can imitate log, should be taken into account its thickness that he has at a high point.

Examples of calculations using the formulas of 1 m3 of the forest, as well as a price comparison

Any specialist since the times of school is known exactly how to calculate the cube or how much in 1 Cuba boards. To make it necessary to find the product of 3 values: height, length, widths. The same method is used to calculate the cubature of a unit. By making calculations more conveniently, the parameters are immediately transmitted to the "meter".

For example, the cubature unit of a material having a length of 6 m and the cross section of 150x25 is calculated as follows: 0.15 m x 0.025 m x 6 m;

The formula of which we will calculate this - V \u003d L * H * B (where L is Length, H - Height, B - Width)

As a result of calculations, 0.0225 m3 is obtained. This is a cubature of one product. If you want to know the cost, then 0.0225 must be multiplied by the cost of 1 cubic meter. After computation, it will turn out that if you miss - a cube will cost 6,500 rubles. And the price of one of them will be 146 rubles. 25 cop. Here for the intense people a small cunning sellers are lurking.

Usually, the cube can be rounded to 0.023. And this means that the sawn timber will cost for the buyer 149 rubles. 50 kopecks Sometimes unscrupulous vendors can round the cube with a size of 150x50 mm to about 0.05 m3. But if all the calculations from the very beginning to perform correctly, it turns out that with the correct count, the result is only 0.045 m3.

It seems well, and what, someone will say! The numbers are small, but the result is stupid! Such rounding will involuntarily lead only to the fact that the price of the unit will be already 325 rubles. instead of 292 rubles. 50 kopecks And these calculations are performed considering that the price of the Cuba is 6500 rubles.

In addition, it is still necessary to know and take into account that the boards having a nominal length of 6 m in reality have a length of 6.1-6.2 m. With lumber sales, this should not be taken into account! Sometimes customers may ask to find out: how many in Cuba boards. This applies to the acquisition of a larger number of boards.

Everything is perfectly visible on the example of the purchase of boards with dimensions of 150x25 mm, where they are in Cuba 44.4. But after all, only 44 boards are considered most often for the cube. And with the right count, this number is as 0.99 m3. In fact, it turns out for 1 cubic meter overpayment. It is approximately 1% of its initial cost. It will look like this: what instead of 6435 rubles. For 1 cubic meter will cost 6500 rubles.

The volume of the umbered forest is calculated completely differently. If you buy one of them, then the measurements of thickness and length of it are performed as accurately as at the edged lumber. But the width of it takes averaged. That is, it is between the smallest and largest. Example: At one end of its end, the width is 30 cm, and on the other about 15 cm, then to calculate the cube, this parameter will be 22-23 cm.

If you need to find out the volume of a large number of timber or determine how many boards will be in volume, they should be decomposed on the stacks. But so that the greatest of them would not differ from the narrow more than 10 cm. In such a stack, the length of them should coincide. But it is only approximately! After that, the tape measure should be measured the height of the stack and its width. These measurements are performed somewhere in the middle, the same concerns the length.

The resulting calculation result should be multiplied by the coefficient. It is from 0.07 and to 0.09. It depends on the air gap, which is between the material. When performing calculations, the greater the size of the gap, the smaller the coefficient takes. If it has the same size, then you can determine the number of boards in Cuba.

By the way, for such calculations there are special tables in the textbooks of builders. Such tables exist practically for all lumber from and ending. They indicate the cubature of common types of timber or other species. And calculate the volume of boards, for example, for the fence is not difficult! You can use the above formula yourself!

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.

To understand how many boards in a square meter, how many cubes of the material are needed to implement one or another project, how many squares can be seen one cubic meter, etc., should anyone who plans to build or repair. And even today it is easy to find table values \u200b\u200bfor almost any situation, it is advisable to still understand how calculations are carried out, and if necessary, be able to calculate their own hands.

Dimensions of the boards

Cubometer board - how much? One of the most common issues that master newcomers are asked. In fact, this question can be given an extremely simple answer: that's, it depends on what lumber speech!

As a rule, billets produced according to GOST 8486-86 are used for construction and repair work. This standard regulating the basic requirements for lumber of coniferous rocks (for deciduous there is a separate document - GOST 2695-83), determines which size can have a product.

In principle, it is easy to choose the desired detail, but still there are certain limitations, which limit the production of blanks:

• thickness - from 16 to 75 mm;
• width - from 75 to 275 mm;
• length - from 1 to 6 m.

Naturally, there are and retreat. So, if necessary, you can order the manufacture of parts with another ratio of thickness and width. Their price, of course, will be higher than standard, but if necessary and the availability of suitable raw materials, you can cut almost any billet.
