How many gallons in 4'x19' pool of water?

Answer 1

Average Depth = Deep End (feet) + Shallow End (feet) divide by 2 Rectangular / Square Pool: Length (feet) x Width (feet) x Average Depth x 7.5 = Total gallons Circular Pool: Diameter x 2 x Average Depth x 7.5 = Total gallons Oval Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons Kidney Shaped Pool: Width of Shallow End (feet) + Width of Deep End (feet) x Length of Pool x 0.45 x Average Depth x 7.5 = Total gallons Free Form Pool: Max Length (feet) x Max Width (feet) x Average Depth x 7.5 = Total gallons

Answer 2

I am assuming the pool is 19-ft diameter and 4-ft deep. If so, the volume of the pool is 1134.1176 cubic ft (will hold 8484.3337 gallons maximum).
