Question

After making repairs, a swimming pool owner is going to refill the pool with water. The pool's dimensions are 18\times40\times618×40×6 feet, with each cubic foot equivalent to 2.642.64 gallons, and the cost of water \$0.005$0.005 per gallon. To the nearest dollar, what is the estimated cost of filling the pool?​

Answer 1

$57

Explanation:

I'll assume the pool's dimensions are 18 x 40 x 6.

The total volume is (18 x 40 x 6) = 4320 ft^3.

Use the conversion factor (2.64 gallons/1 ft^3) to find the gallons of water in a full pool. Full pool, cool.

Water (gal) = (4320 ft^3)*(2.64gallons/ft^3) = 11,405 gallons

At $0.005/gal, this would cost (11,405 gallons)*($0.005/gal) = $57.02

$57 to the nearest dollar.
