Find the length and volume ?

Question

The surface area of a cube is 384 cm square . Find

the length of an edge

volume of the cube

Answer 1

A cube has 6 sides with equal surface area.

Surface area of each side
= 384 cm^2 / 6
= 64 cm^2

Since this is a cube, each side will be a square surface.

Thus, length of cube
= sqrt(surface area of each side)
= sqrt(64 cm^2)
= 8cm

Volume of cube
= length * length * length
= 8cm * 8cm * 8cm
= 512 cm^3
