Exponent form of the volume is 
Volume of the cube is
inch³.
Step-by-step explanation:
We are given,
A cube with side equal to
inches.
As we know,
Volume of a cube = 
Thus, we get,
Volume of the given cube is,
Volume =
i.e. Volume =
inch³
Thus, we have,
The power for the volume of the cube is '3'.
Exponent form of the volume is 
Volume of the cube is
inch³.
