An indoor swimming pool is 12 feet in width by 30 feet in length. The shallow end is 3.5 feet deep and the deep end is 8 feet deep, and the depth of the pool changes linearly from the deep end to the shallow end.
One standard box of Jell-O brand gelatin (6 ounces) makes four cups of Jell-O when set up.
Calculate the number of boxes of Jell-O which would be required to completely fill the swimming pool. Assume that the volume of the filtration equipment is negligible and that the pool is to be filled with Jell-O completely.
Conversion factors you may need:
1 cubic foot = 7.481 gal
1 gal = 16.0 cups
A) One package of Jell-O, prepared according to the directions, makes 8 servings of Jell-O which each have 80 calories. What would be the total caloric content of the swimming pool so filled?
B) If a standard caloric intake for an adult is 2000 calories per day, for how many days could a single adult live off of the swimming pool filled with Jell-O? Assume that there is no spoilage and that the Jell-O in the swimming pool is nutritionally adequate to support life.
