### 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.

### How many gallons of water will it take to fill a 14x42 pool?

You need to know the average depth of the pool. the depth of the
deep end plus the depth of the shallow end divided by 2 will give
an average.
The formula for estimating the gallons of water is in a pool
is;
length times width times average depth times the multiplier 7.5
for a rectangle pool; 6.7 for a oval or free form pool.
with this formula a rectangle pool 14X42 6 feet deep end and 3
feet shallow end will be approx. 19,845 gallons
