80 if the tiles are 12x12 - 12x12 is one square foot covering 80 you would need 80 tiles
A 3x12 room is 36 square feet. This means that to fill the floor in the 3x12 room, it will take 36 tiles that are each 1 square foot (12x12) in size.
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?
Since a 12x12 tile is one square foot, then 38 12x12 tiles will cover 38 square feet.
