Ashley has a new aquarium. The tank is in the shape of a rectangular prism, 84 in long, 36 in wide, and 48 in deep. She plans to raise fish and sell them to a local pet store. The pet store will inspect the aquarium to make sure that the fish are being kept in a healthful environment. One of the main concerns is that
each fish has enough water. Ashley looks up the amount of water needed for the species of fish she plans to raise. She finds the answer, but it is given in cubic
feet.
