The answer will depend on the units for 2. Whether it is 2 inches, feet or something else. Assuming you mean feet, a 12 foot x 12 foot x 2 foot area contains 288 cubic feet. Sand is usually measured in lbs. One cubic foot of sand weighs about 100 lbs (see related questions below). 288 x 100 lbs = 28800 lbs. This is 14.4 tons of sand.

Concrete is a mixture of sand, gravel, cement, and water. Generally, you have 1 part cement, 2 parts sand, and 3 parts gravel. Sand makes up about 1/4 or 1/3 of a cubic foot. At 100 pounds per cu ft that is about 25-35 pounds.
4 inches deep would be the minium coverage of sand needed for a horse area
As you did not specify a depth, I can not provide an answer.

use a known volume container to measure a quantity = 200 x (the depth you want the sand).

To determine how much sand you need for a 62 sqm area, you should calculate the depth of the sand layer you want to spread. For example, if you want a 5 cm layer of sand, you would need 3.1 cubic meters of sand. Make sure to account for compaction and settling when estimating the amount of sand needed.

Four cubic yards will do it. You theoretically need only 3.7, but that assumes the area you're putting the sand in is perfectly level, flat and low-spot-free...and they never are.

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.
