Final answer:
The power that can be used to represent the volume of a cube is the power of 3.
Step-by-step explanation:
To represent the volume of a cube, you can use the power of 3. This means that you need to cube the length of one side of the cube. For example, if the length of one side is 4 units, then the volume of the cube would be 4 cubed, which is equal to 64 cubic units.
