You don't use sand to level the ground that the pool sits on. The sand is used on the inside of the pool, after the ground has been leveled by taking the highest point down to the lowest point after the grass has been removed. The manufacturer's usually recommend 2" of sand on the inside of the pool before the liner is installed. It sounds like you are installing a used pool, since you do not have instructions. Here is a link to some instructions that could possibly be used. http://www.royalswimmingpools.com/install.htm
5300 gallons
The dimensions of the pool are needed to calculate this Well actually depends how big and how much u put in to it!
1 foot by 36 sq feet = 36 cubic feet of dirt is needed
From $500 up to whatever needed depending on the conditions.
You need three measurements, length, width, and depth, to calculate the volume of the pool
One foot
160 of them.
Children under 16 its free
Diameter x Diamater X Depth X 5.2

You will need 1500 cubic feet.
I'd estimate around 19,278kwh per day.
