Question

The volume of a cube is 0.015625 m3. Determine the length of each side

Answer 1

l x w x h is the formula for a cube, and considering a cube's l w and h are equivalent, each side is the cubic root of the area. So each side is 0.25 m long.

Answer 2

`a-the\ length\ of\ each\ EDGE\ of\ the\ cube\\\\The\ volume:V=a^3\ \ \ (V=0.015625\ m^2)\\\\therefore\\\\a^3=0.015625\Rightarrow a=\sqrt[3]{0.015625}=\sqrt[3]{(15625)/(1000000)}=\frac{\sqrt[3]{15625}}{\sqrt[3]{1000000}}=(25)/(100)\\\center=\boxed{(1)/(4)\ (m)=0.25\ (m)}`
