A right triangle prism has a volume of 2 cubic inches. A second right triangle prism is similar to the first one and has a volume of 128 cubic inches.
A. What is the scale factor to go from the first prism to the second?
B. What is the scale factor to go from the second prism to the first?

since the volume scaled by 64, the side length scaled by 4.
1/4 to go the other way.
