At the marine park, one of the aquariums is
shaped like a rectangular prism. The inside
dimensions are 22 feet long, 9 feet wide, and
7 feet high to the water line.
9 ft
22 ft
7 ft
Which equation could be used to find the
volume of water that would have to be re
moved to lower the water level to 5 feet?

volume of the full tank = (9)(22)(7) ft^3
volume at 5 ft high = (9)(22)(5)
subtract the two volumes
