Hassan's backyard swimming pool is 30 feet long, 20 feet wide, and 5 feet deep. There are 7.5 gallons of water in 1 cubic foot. How many gallons of water will the pool hold?

Answer 1

`1.Calculating\ volume \ of \ the\ swimming\ pool:\\\\ V=a*b*c\\ a=30 feet,\ b=20feet,\ c=5feet\\\\ V=30*20*5= 3000 feet^3\\\\ There\ are\ 7,5 \ gallons\ of\ water\ in\ 1 \ cubic\ feet\ so:\\\\ V*7,5 gallons=3000*7,5=22500 gallons\\\\ Answer:\ 22500\ gallons\ swimming\ pool\ can\ hold.`

Answer 2

Volume = (L x W x D) x (7.5 gal/cubic-ft) = (30 x 20 x 5) x (7.5) = 22,500 gallons
