The length of timber cubic meter is 2.6 meters and the perimeter is 14 cm
Radius = 14cm / 2 / 3.14 = 2.23cm = 0.023
Volume = 0.023 * 0.023 * 3.14 * 2.6 = 0.004318756 M3
As shown in the figure, it is a rectangular timber with square cross section. How many cubic meters is the volume of this timber? How many cubic decimeters is it?
It is 10 / 3 in length, 3 / 5 in width and 3 / 5 in height
10 / 3 * 3 / 5 * 3 / 5 = 1.2 cubic meters = 1200 cubic decimeters
