How to Calculate Cubic Meters of Lumber By Larry . Calculate the area of the tree at breast height by dividing the diameter at breast height by two, squaring that number, and then multiplying the result by 3.1415. Multiply the area by the merchantable height of the tree. Take the result and multiply by 0.7 to allow for the natural tree taper .

19th century, when logs tended to come from old-growth trees of large girth, and residues from milling them for lumber had little value.
