If the tiles are 12 inches square... 8352 tiles ! However if they're 12 feet square... 58 tiles
assuming that's 12feet x 12feet, 16 square yards.
123 will cover it. Get extras.
Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles

If you're talking floor tiles as opposed to wall tiles and by 12x12 you mean they are 12 inches square, then the answer is 300. Because each tile is one square foot and a 15'x20' room is 300 square feet. Simple, eh?
Well if 12x12 is one square foot and you have 44 you need to cover figure 10% for breakage (5 tiles) it looks like 50 tiles will do ya
If the tiles are 12x12 inches square - you would need... 75 !
