===================================================

Explanation:

Cubing something means we multiply it by itself 3 times.

A few other examples are shown below

[tex]\text{five cubed} = 5^3 = 5*5*5 = 125\\\\\text{eight cubed} = 8^3 = 8*8*8 = 512[/tex]

As the name "cubed" implies, this concept is useful to find the volume of a 3D cube where all the side lengths are the same.
