The level of water in a rectangular swimming pool needs to be lowered 4.00 inches. If the pool is 36.50 ft long and 15.00 ft wide, and the water is siphoned out at a rate of 5.0 gal/min, how long will the siphoning take?

Question

1 ft^3 = 7.48 gal.

Now convert ft^3 to gal. there are 7.48 gallons per ft^3

Now,
