Hans has a new aquarium. The tank is in the shape of a rectangular prism, 5 ft long, 2 ft wide, and 3 ft deep. He 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. Hans looks up the amount of water needed for the species of fish he plans to raise. He finds the answer, but it is given in cubic inches. (a) Find the volume of water that the tank holds in cubic inches. Use the table of conversion facts, as needed. (b) The particular species Hans plans to raise requires at least 690 in. of water per fish. If there is any amount less than this, no matter how much less, the pet store will not accept Hans's fish. What is the largest whole number of fish that he can keep in the aquarium? (c) The pet store will pay $1.79 for each fish. If he fully populates his aquarium and sells all the fish, how much money will he collect?
