It would cover 144 square centimeters.
104.0625 tiles exactly (so - 105 tiles in all)
Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
15'x15' is 225 square feet; so I would figure on 225 tiles. I would get a few extras in case some crack.
Each 16 inch tile is 1.78 square feet. You would need 169 tiles, plus some for spoilage.
49 tiles
25 geinus
81 tiles squared because if it's a square then it would be 9x9 which is 81
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
640
500/1.78 = 281 tiles
a 12 x 12 tile is 1 square foot. So, you would need 300 tiles to cover 300 square feet
11 feet x 14 feet = 154 square feet. You would need 9 tiles, that measured 4 inches x four inches, to cover one square foot. So you would need 154 x 9 tiles to cover the entire area, which is 1386 tiles.
If the tiles are 1 foot squares, it will take 1,650 of them to cover 1,650 square feet. If the tiles are 16 inch square (1-1/3 square feet, each), then it would take 1,238 tiles.
You will need at least 66,828 1/4 tiles to cover that area.
