The length of timber cubic meter is 2.6 meters and the perimeter is 14 cm

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
