A water tank is built in the form of a right rectangular prism, with dimensions that measure 13.4 ft by 8.7 ft by 7.5 ft. How many cubic feet of water would it hold when it is full? Round your answer to the nearest tenth if necessary.

To find the volume of the water tank, we need to multiply the length, width, and height of the prism.

Volume = length x width x height
Volume = 13.4 ft x 8.7 ft x 7.5 ft
Volume = 826.11 cubic feet

Therefore, the water tank would hold 826.1 cubic feet of water when it is full.
