# If the depth of a 40ft by 20ft rectangular pool varies from 9ft at the deep end to 4ft at the shallow end how many gallons of water will fill it?

Answer .
If we assume that the bottom of the pool is a flat surface, then its average depth is 6.5 feet. Its capacity is therefore:.
6.5 x 4 x 9 = 5200 cubic feet..
The n…umber of gallons to which this is equivalent depends on the type of gallon. There are about 6.23 Imperial UK gallons to the cubic foot, yielding an answer just short of 32390..
However, there are 7.48 U.S. liquid gallons per cubic foot, and this gives us a figure of nearly 38899.

# How many gallons to fill a 25 x 50 ft pool with a deep end of 9 ft and shallow 3 feet deep?

Not knowing the point where the pool begins the transition from 3 feet to 9 feet makes it a little hard to answer..
If it slopes directly from 3 to 9 feet the answer would be… approximately 56,250 gallons..
The calculation for a rectangle pool is: ((Shallow end depth + deep end depth) / 2) * length * width) = pool volume in cubic feet.
Pool cubic feet * 7.5 = gallons of water the pool holds.

As long as the slope of the bottom is constant and continuous, with no flats or sudden drop-offs, we can treat the whole pool as if its depth is the average of 3-ft and 8-…ft = 5.5-ft. Volume = 20 x 40 x 5.5 = 4,400 cubic feet = 32,914.3 gallons (rounded) Note that this is the volume of the pool, not necessarily the amount of water in it.
