Here are the answers to today’s practice problem.To answer these questions I would convert the measurements in inches to feet:
60 inches ÷ 12 inches/foot = 5.0 feet
90 inches ÷ 12 inches/foot = 7.5 feet
72 inches ÷ 12 inches/foot = 6.0 feet1. What are the gallons per inch for this tank?
To determine gallons per inch take the length x width x 1 foot/12 inches x 7.5 gallon/cubic foot
5.0 feet x 7.5 feet x 1 foot/12 inches x 7.5 gallons/cubic foot = 23.43 gallons per inch2. What is the operating volume of the tank?
Operating volume is the length x width x depth
