Question

Find the length of each side of a cube if its volume is 512 cm³.

Answer 1

From the question it is given that, 

Volume of the cube = 512 cm³

We know that,

Volume of cube = side³

512 = side³

By taking cube root on both the side,

`root(3)(512)` = side

Side = `root(3)(8 xx 8 xx 8)`

Side = `root(3)(8^3)`

Side = 8 cm

∴ The length of each side of a cube is 8 cm.
