b. How many cubic feet of water are in the pool? (3 points)
Volume: __________ ft3
c. If one cubic foot contains about 7.5 gallons, how many gallons of water are in
the pool? (3 points)
Water: __________ gallons

Answer 1

a. Length = 25 yds. × 3 ft./yd. = 75 ft.

Width = 8 × 3 yds. × 3 ft./yd. = 72 ft.

b. Volume = 75 ft. × 72 ft. × 6 ft.

= 32,400 ft.^3

c. (32,400 ft.^3)(7.5 gal./ft.^3)

= 243,000 gal.
