A 19.75 x 19.75 inch tile covers 390.0625 square inches, or 2.70877 square feet (divide by 144, which is 122, since we're working in square quantities). 1000 / 2.70877 = 369.171 tiles to cover the given area. (Were you to purchase tiles to actually do this, you'd haver to buy at least 370 tiles, since you can't buy 0.171 tiles.)
Just multiply 20 by 20 to find that each tile has 400 square feet to it. Then divide 1000 by 400 to find that you'll need 2.5 tiles -- so you should buy three.
1000 square feet of sod, or 111 square yards
Area of each tile = 30*30 = 900 mm2. Area to be covered = 1000*1000 = 1,000,000 mm2 So, number of tiles required = 1,000,000/900 = 1111.11... tiles.
3000 sq ft * 4 inches = 1000 cubic feet.

36" = 3 ft 36" x 36" = (3 ft) x (3 ft) = 9 square feet per tile 1000/9 = 1111/9 tiles. Either buy 112 of them, or else buy 111 and plan your work carefully so that the one bare square foot winds up under the refrigerator or the bed.
Just multiply 20 by 20 to find that each tile has 400 square feet to it. Then divide 1000 by 400 to find that you'll need 2.5 tiles -- so you should buy three.
It depends on the units used for measuring the tiles. Obviously, the number of 18 inch x 18 inch tiles required will not be the same as 18 cm x 18 cm tiles. And if there were 18 yard x 18 yard tiles, you would need only 1.
