After cutting a tree trunk, a slab is left on the boards - sawn timber waste, which is not a full-fledged high-grade wood. Nevertheless, there is a demand for them in construction and finishing.

Why know the volume?

Croaker is subdivided into business and low-grade. The first one is used as a cheap substitute for edged boards - where perfect evenness, neatness of construction or construction is not required . The second - for chips, sawdust, shavings and firewood. The croaker is the chipped part of the board, one edge of which is rounded, and the other is sawn, even. Before stacking, the bark is removed from it.

The volume of the slab in a stacking cubic meter must be known in order not to pay for air . The fact is that the slab comes in different sizes, and the consumer pays only for the wood - and not for the gaps between the pieces of wood. The actual volume of wood is needed to find out the cost of delivery of a given building material: it is measured mainly in cubic meters.

Weight in tonnes is only used internally to calculate shipping costs based on gasoline (or diesel) costs.

How many pieces of different slabs are in 1 cube?

To calculate how many pieces of slab in one cubic meter, they operate with the concepts of a fold and a compacted cube. The first is cubic meters of boards laid with permissible (spacer for ventilation and drying) voids. The second is the same wood, but without voids. The simplest method of calculating, for example, the density of pine (15% water - considered dry) is 510 kg / m3 . A cubic meter of such pine in boards, laid tightly, end-to-end - 510 kilograms per cubic meter, approximately half a ton per "cubic meter". Dividing this number by 1.43 (the folding parameter on average), we get 356 kilograms of pine slab per cubic meter.

For example, two-meter slab boards, on which the remains of the harvested timber obtained in this way are sawn, can be stacked at 50 pieces per cubic meter. The thickness of the trunk of the same pine is a variable value: due to the width and thickness of the tree rings, individual pines could grow unevenly, and the size (and with it, the weight) of the trunks of pure wood can differ significantly. Dividing the same 356 kg into 50 two-meter slab cuts (or 33 with a small remainder - 3 meters each), we get 7, 12 kg for a slab board. In this case:

• 5 cubes - 250 boards - about 1780 kg of slab wood will come out;
• 6 cubes - 2136 kg;
• 30 cubes in tons - 10680 kg of slab - more than 10 tons will be released (a truck with a tractor for delivery may be required, without a trailer);
• a smaller value, for example, 7 cubes, will come out for pine - according to the same formula - 2492 kg, that is, almost 2.5 tons.

How to calculate correctly?

You can calculate the cubic capacity of wood in several different ways, but they all take a lot of time. Even an experienced storekeeper will not be able to immediately determine by eye how many kilograms of slab in a cubic meter. Consider the steps for calculating a business slab.

• Sawed boards are sorted by length - up to 2 meters and over 2 meters in length.
• The bark is removed without fail - mainly the volume and weight of the wood are estimated. Not everyone will undertake to use bark for construction purposes, so it only goes for heating for solid fuel boilers.
• The slab is stacked with the smallest (if possible) voids. The boards are laid in different ways, given their imperfect convex surface. It is imperative to dock along the length of the segments (trimming). The corners of the stack are straight, the edges of the cube (or parallelepiped) are even, without bevels.
• The width and length are multiplied by the height - the fold volume of the slab is obtained.
• The values obtained are divided by 1, 43.

The resulting value is the dense cubic capacity of wood. If the volume is small, then in order to eliminate errors in the recalculation, it is advisable to weigh the stacks on a truck scale, using a forklift or truck crane available in the warehouse. Dividing the weight of the stacks by the density of dry wood (in this case, pine), we have the actual (dense) volume of the slab. Unlike straight boards, which have a constant volume and dimensions, measuring a slab is not an easy task.

The above estimates are approximate, the exact volume is determined only when weighing.
