Recently, one of the users asked to calculate "Calculation of: How many cubic meters in a single plank; the calculation of the cubic capacity of the lumber, in general". And another asked - "How many wooden planks (under certain sizes) in one cubic meter".
These tasks are reversed so there are two calculators. First one was this - Calculation of volume in cubic meters by the size of one unit of output
and then I've decided to publish them both.
So, the first calculator calculates the volume by the size of the plank and overall amount of planks and the second one calculates approximate amount of planks (rounded down) by the size of the plank and overall volume. By these, I hope, I dropped the subject of planks and cubic meters.
