Math is used here every day -- in converting fresh to salt water, filling tanks, establishing displays, feeding and other ways. The largest life support system here contains 36, 485 gallons of water, the smallest 30 gallons.
1. A fish tank 5 feet long, 21/2 feet wide and 3 feet deep is being filled from a pipe which discharges 18 quarts of water a minute. How long will it take to fill the tank if 1 cubic foot = 71/2 gallons?
2. A cylindrical tank has a radius of 1 yard and a height of 4 feet. What is the weight of the water when the tank is half full, if 1 cubic foot of water weighs 621/2 pounds? (Use pi = 3.14)
