The two prisms (see below) are similar. The larger one has a volume of 64 cubic feet and the smaller one has a volume of 27 cubic feet. If the larger one has a height of 10 feet, what is the height of the smaller one?

Answer:
7.5 feet
Step-by-step explanation:
large over small=64/27
r:4/3
4/3=10/h
4h=30
h=30/4
h=7.5 feet
