Your pool's volume is 40ft x 16ft x 5.75ft = 3680 cubic feet.
1 cu.ft. = 1728 cubic inches
1 US gallon is 231 cubic inches
3680 x 1728 / 231 = 27528.312 US gallons in that pool.

23.5 feet. This assuming that the 52 is inches.
A round pool 30 feet wide and 52 inches deep can hold a maximum of 22,700 gallons of water.
40 square feet * 2 inches = 40*(1/6) = 6.66... cubic ft = 41.5 UK gallons or 49.9 US gallons (approx).
2 feet 6 inches deep
28,913 US gallons.

To answer that we would need to know how deep the water is, and if the measurements are in feet or inches.
The aquarium would have a volume of 2200 cubic inches. One cubic inch is 0.0043290 liquid gallons, so 2200*0.0043290 = 9.52381 gallons.
40 square feet * 2 inches = 40*(1/6) = 6.66... cubic ft = 41.5 UK gallons or 49.9 US gallons (approx).
2 feet 6 inches deep
'bout 1500 to 2000
