How many gallons of water does it take to fill a rectangle pool 18x36 with a 3 foot shallow end and a 8 foot deep end?

Assuming brim-full,

30x3 = 90 ft2

30x4/2= 60ft2

90+60=150ft2

150x15=2250ft3

2250ft3 = 14014.8675 UK gallons

2250ft3 = 16831.17 US gallons

Answer:

area on top = (18x36) ft squared = 648 ft^2

vol of top section = 648x3 = 1944ft^3

vol of (bottom) diagonal section is: 0.5(36x18).(8-3) = 1620ft^3

total vol = 1944 + 1620 = 3564ft cubed

3564 (feet cubed) = 22 199.5604 Imperial gallons

what I did was split the volume of the pool into two sections and deal with them independently as two separate shapes.

You need also to specify the depth.

It depends on how deep it is. But probably around 30,000 gallons

That will depend on how deep you want the water to be.

Length x width x average depth*. Multiply result by 7.48 to determine volume in gallons. * 'average depth' is shallow end + deep end divided by two

Need to know the depths of the shallow and deep end, and the shape of the pool, whether it is a rectangle or kidney or irregular shaped.
