Here's a formula for round pools:
distance across*distance across*depth*5.9
for rectangles:
length*width*depth*7.5
or for a deep end:
length*width*((shallow end depth + deep end depth)/2)*7.5
so in your case, 16*16*4*5.9=6000 gallons=23000 liters
5,310 gallons.
A 22-foot round pool that is 4 feet deep holds about 43,238.5 liters of water.
About 49,246.3 liters of water.
About 129,715 liters.
About 39,397 liters.
About 45,025 liters.
right at 1809,000 liters
There are 3,634 liters (960 gallons) of water in a pool that is four feet in diameter and 8 feet deep.
That would depend what shape and how deep the pool is.If it is a round pool, 18 feet across and 4 feet deep, you would have 1000 cubic feet (pi R squared D), which is 28,300 liters.
Approximately 20016.7 liters

The answer depends on how deep the sump is!
If it is a round pool that is 10 feet wide and has 3 feet of water then it contains 1,770 gallons of water.
