Question

A new swimming pool is an 18 feet wide and 36 feet long rectangle with varying depths. If 1 cubic foot= 7.48 gallons of water, how many gallons of water will be needed to fill the pool, to the nearest gallon

Answer 1

gallons of water will be needed to fill the pool 19388.16 gallons

Explanation:

given data

Length of rectangular pool = 36 feet

Width of rectangular pool = 18 feet

1 cubic foot = 7.48 gallons water

solution

we consider here Depth of rectangular pool = 4 feet

so Volume of the pool = Length × Width × Depth ..............................1

put here value

Volume of the pool = 36 × 18 × 4

Volume of the pool = 2592 cubic feet

and

1 cubic feet = 7.48 gallons

so 2592 cubic feet will be

2592 cubic feet = 7.48 × 2592

2592 cubic feet = 19388.16 gallons
