The area of one side of a cube is $16{\mathrm{ft}}^2$. What is the volume of the cube?

A cube has 4 equal sides. The area of any side of a cube is side squared (s²). If one side of a cube has an area of 16 cm², take the square root to get the number of cm on each side of the base, which is also the number of cm on each side of the entire cube.

side $=\sqrt{16}=4$

The volume of a cube equals side cubed (s³).

volume $=\left(4\text{ ft}\right){}^{\text{3}}=64{\text{ft}}^{\text{3}}$
