Simple Cube Volume
A cube with a side length (S) of 2 has a volume (V) of 8.
Rectangular Prism Volume
A rectangular prism with a length (L) of 2 a width (W) of 3 and a height (W) of 4 has a volume (V) of 24.
A cube has three equal sides (S), this means the volume can be determined by multiplying Side x Side x Side, this is the same as Side3.
If one of the sides is not the same then this is a rectangular prism. The volume of a rectangular prism can be determined by multiplying Length (L) x Width (W) x Height (H).
