A 12 inch by 12 inch tile is 1 ft by 1 ft, which is 1 square foot. So you would need 120 tiles.
A 24 inch tile x 24 inch is 2 ft by 2 ft = 4 square feet 648/4 = 162 tiles
20 inches = 20/12 ft = 1.67ft6 inches = 6/12 ft = 0.5ft1.67X0.5 ft = 0.83 sq ft.Therefore 900sq ft / 0.83 sq ft = 1080 tilesHowever the above answer is how much is needed without waste. I.e. no partial tiles for the perimeter.
Length (ft) x Width )ft) = Area (sq ft); 8 x 6 = 48 sq ft; Assuming the 6-inch tiles are square, then 4 tiles = 1 sq ft Multiply 48 sq ft x 4 tiles per sq ft to determine: 48 x 4 = 192 tiles
The number of tiles required will be different if they are 20 inch x 20 inch tiles rather than if they are 20 cm x 20 cm tiles. Also, the answer depends on whether the room is 12 foot by 8 ft or 12 metres x 8 metres. In the extreme case, you would need only a single 20 ft x 20 ft tile for a room that is 12 ft by 8 ft.

To find out how many 20-inch tiles you will need to cover 100 sq ft, you first need to calculate the area of one tile. A 20-inch square tile covers 20 x 20 = 400 sq inches. Since 1 sq ft = 144 sq inches, you divide 400 by 144 to get approximately 2.78, meaning it will take about 2.78 tiles to cover 1 sq ft. Therefore, to cover 100 sq ft, you will need about 278 tiles.
1120 plus 10% for salvage= roughly1230tiles. you can probably return unused tiles

You would need 173 tiles (you would have fractions of tiles left over)
8 ft 6 in X 12 ft = 102 sq ft 102 sq ft X 4 tiles/sq ft = 408 tiles Get a few extra in case some crack. You may be glad later that you had a few replacement tiles.
