Square yards is a measure of area, you need to purchase your sand as a volume not an area. You will need 2000 cubic feet of sand.
A 2500 square foot area x 4' deep is 10000 cubic feet. So you need 10,000 cubic feet of sand. Dry sand has a density of 80-100 pounds or so per cubic foot, so that's somewhere between 800,000 and a million pounds of sand.
The answer will depend on how deep the cement needs to be.

You need to mention how deep you want the sand to be
1 yard = 3 feet1 squared yard = 3 square feet
one ton of sand covers about 100 square feet which is about 9.3 square meters.
100 x 1/4 *1/12 = 2.08 cu ft = about 208 pounds of sand
Volume = (base area) x (height) = 300 cubic feet = 111/9 cubic yard.
