A fish tank is 28 inches tall and has a base that is 17 inches by 21 inches. You want to fill the tank to a depth of 26 inches. How much water will it take?
Since we want to fill this tank to a depth of 26 inches, and the base of the tank is already given, we just need to multiply the dimensions to find how much water we need:
17 x 21 x 26 = 9282 inch3 of water.
