A 12 x 12 tile covers one square foot. So you need 432 of them, plus some for spoilage.
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.
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?

If they are 12 inches x 12 inches then you would need 399 tiles.

If the tiles are 12 inches square... 8352 tiles ! However if they're 12 feet square... 58 tiles
To determine how many 12x12 tiles are needed for a 54 square foot area, first calculate the area of one tile. A 12x12 tile is 1 square foot (since 12 inches is 1 foot). Therefore, to cover 54 square feet, you would need 54 tiles, as each tile covers exactly 1 square foot.
