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!
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
