If the tiles are 12 inches square... 8352 tiles ! However if they're 12 feet square... 58 tiles
A 12x12 tile is 1 sq foot, so you will need 198 tiles.
To determine how many 12x12 tiles cover 144 square feet, first calculate the area of one tile. A 12x12 tile has an area of 1 square foot (12 inches x 12 inches = 144 square inches, which is 1 square foot). Therefore, to cover 144 square feet, you would need 144 tiles, since 144 square feet divided by 1 square foot per tile equals 144 tiles.

Oh, isn't that just a happy little question! If you have 38 tiles that are each 12x12 inches, they will cover a total of 38 square feet. You see, each tile covers 1 square foot, so when you multiply 38 tiles by 1 square foot, you get 38 square feet. Just imagine all the beautiful patterns and designs you could create with those tiles!
If the tiles are 12x12 inches square - you would need... 75 !
Each tile will be one square foot. So you have 135 square feet.
