An in-ground pool that is 40 feet by 20 feet with the shallow end being 3ft deep and the deep end being 9ft deep has a volume of approximately 35,900 US gallons. (The depth of variable depth pools is generally calculated by adding the shallow and deep ends and dividing by two).
To determine the volume it is necessary to know the depth at the shallow end and also whether the slope of the bottom is smooth all the way.

Cannot be answered without knowing the shallow and deep end depths.

Not enough information. need length and width
The question cannot be answered with the information given. It is necessary to know the length and width of the pool as as as whether or not the depth increases steadily.
To determine the volume it is necessary to know the depth at the shallow end and also whether the slope of the bottom is smooth all the way.

It can be shallow or deep.
14,949 gallons. 4,147,200 in^3, with 0.00360464866 gallons per in^3.
If the pool is 8 feet in the deep end and 3 feet in the shallow end, the total volume will be about 21,722 gallons of water.
