depends how deep it is, but generally it's
20' x 40' Rectangle = 30,000 Gallons

A lot. I have been pumping one that size out that has been abandoned for several years and it is full of leaves so that doesn't help. How much water is in it depends on the design of the pool: how deep the deep end is, how shallow the shallow end is, and what sort of a trasition there is from shallow to deep.
When I started pumping this thing out I dropped the pump into the deep and and just let it run. For several days I ran it for 3-4 hours per day, pumping out at the rate of at least 30gpm, probably more. Finally after about 5-6 days the shallow end was dry and it began to go a lot faster after that, but it took a lot of pumping to get that far.
A 20x40 foot pool has a surface area of 800 sq ft. A depth of 4 feet overall would mean 3200 cu ft, plus whatever is in the part deeper than that. It is hard to guess without knowing the profile of the pool.

This is the formula that a pool pro uses.
Length X Width X Average Depth X Multiplier = Gallons in your pool
Determine the Multiplier:
Rectangle, square, or free-form pool:multiplier = 7.5.
Round or Oval pool: multiplier = 5.9
Determine the Average Depth:
To determine the average depth in a pool where the bottom slopes, measure the shallow end, the the deep end depth. Add them together and divide by two (2).
Example: Shallow End = 2'. Deep End = 10'
2' + 10' = 12'; 12'/2 = 6' Average Depth
Put all your variables into the equation at top and you have the answer, good for your particular pool.

How deep is the pool? (Assume in feet?)
Standard Pool In-Ground Pool Sizes with Varying Depths
3.5' DEEP = 21,000 gallons
4.0' DEEP = 24,000 gallons
4.5' DEEP = 27,000 gallons
5.0' DEEP = 30,000 gallons
5.5' DEEP = 33,000 gallons
A cubic foot of water will contain 7.5 gallons. If you have base x width x depth of pool all multiplied by 7.5 that will give precise gallons of water in pool.
Good Luck!

I think, at least 2,000 gal. or more, you have to have a company that delivers water to fill up the pool. It is already treated with the chemicals.
It would take you forever to fill up that pool with a hose, and probably cost you more from where you live than having it delivered.
Good luck.
