Here are the answers to today's practice problem.1. If the pump tank is 50-by-60-by-72 inches deep, calculate the gallons per inch.Convert length and width to feet.(50 inches ÷ 12 inches per foot) = 4.2 feet
(60 inches ÷ 12 inches per foot) = 5 feet
(72 inches ÷ 12 inches per foot) = 6 feetCalculate volume (cubic feet) in 1 foot of depth.4.2 feet x 5 feet x 1.0 foot = 21 cubic feetConvert to volume in gallons.21 cubic feet x 7.5 gallons per cubic foot = 157.5 gallons per footCalculate gallons per inch.157.5 gallons per foot ÷ 12 inches per foot =
