If you mean 12x12 "inches", then each tile covers 1 square foot. We trust you can take it from there.
If 12x12 is 144... There would be 144 tiles in a box right?
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?
12X12 12X12
12x12= = 144
