Problem Solving 19. A gallon of water weighs 8.3 pounds. A cubic foot of water weighs about 62 pounds. To the nearest tenth, about how many gallons of water would fill a cubic foot?

To figure out how many gallons of water would fill a cubic foot, you can use the weights of water given. Since a cubic foot of water weighs about 62 pounds and a gallon weighs 8.3 pounds, you would divide the total weight of a cubic foot by the weight of a gallon: 62 pounds / 8.3 pounds per gallon ≈ 7.5 gallons. So, you can fit approximately 7.5 gallons of water in a cubic foot! A common mistake when tackling this kind of problem is forgetting to ensure that the units are consistent. Always double-check that you're comparing the same measurements (like pounds or liters); otherwise, your outcome could be off. Keep your units aligned, and you'll sail through these calculations!
