Final answer:
The volume changes exponentially as the side length of a shape is changed.
Step-by-step explanation:
The change in volume is proportional to the original volume. For example, if the side length of a shape is doubled, its volume will increase by a factor of 8, which is 2³. Similarly, if the side length is tripled, the volume will increase by a factor of 27, which is 3³.
So, as the side length of a shape is changed, the volume changes exponentially.
