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

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

Step-by-step 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
