Jair · Answer 2

You have a rectangular pool 15 X 30 X 5 feet

The floor of the pool is 15X30 = 450 ft2

Two sides are 5X15 = 2 (75) = 150 ft2

Two sides are 5X30 = 2 (150) = 300 ft2

Total area to be painted: 900 ft2

(900 ft2) / (250 ft2/gal) = 3.6 gallons

Since we can't purchase. 6 gallons we

must purchase 4 gallons of paint

The volume of the pool is 15X30X5 = 2250 ft3

1 ft3 = 7.48 gallons

2250 (7.48) = 16,830 gallons of water
