That depends entirely on what kind of sand how deep you spread it. As an approximation, you could assume a bulk density for dry sand of about 110 lb/ft3. One ton (2000 lb) of sand would thus be about 18.18 ft3 or 0.673 yd3. If you spread it 6 inches deep you could cover about 4 square yards. At a foot deep, you would cover 2 square yards. At 3 inches deep you would cover 8 square yards. At 1 inch deep you would cover 24 square yards Reported bulk densities for sand range from 78 lb/ft3 for molding sand to 130 lb/ft3 for moist sand.
630 cubic inches
one ton of sand covers about 100 square feet which is about 9.3 square meters.

Not counting the space for sand between the blocks, it would take11,520/(area of each block in square inches)blocks.
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.
You need to mention how deep you want the sand to be
1 yard = 3 feet1 squared yard = 3 square feet
about 4.8 ton of sand
