If a bathroom is 72 inches by 54 inches, it would take 27 1 foot square tiles to tile the bathroom. This can be found by converting from inches to feet, then calculating area by multiplying the length by the width.
If the tiles are 12x12 inches square - you would need... 75 !
85 square feet is the area of a room that measures eight by ten and a half feet. This is the size of a typical second bedroom. If there was a floor tile that measured 12 inches by 12 inches, this would be 85 floor tiles.
One 9 inch square tile would presumably be 9in x 9in or 81in2, unless you are meaning 3in x 3in tile which is then 9in2. Regardless, the answer to your question is the total area of the floor (in square inches) divided by the total area of one tile (in square inches).
If the carpet tiles you are using are the standard 12" square, then multiple your length and width to get the square footage. In this case your room would need a minimum of 196 tiles. CHeck the box for pattern repeat and remember to add tiles for damage and waste.
One square foot would be 12 inches by 12 inches, or 144 square inches. This means to convert square feet to square inches, multiply the number of square feet by 144 to to get the number of square inches.
If the tiles are 12x12 inches square - you would need... 75 !
If your tiles are 12 inches x 12 inches you would need 144 of them.
You will need at least 66,828 1/4 tiles to cover that area.
Assuming you mean the tiles are 16 inches square - you would need 169 tiles.
776. You need four tiles for one square foot (tiles are 36 square inches, a square foot is 144 square inches) so 4 tiles times 194 sqft is 776. You will want some spares too.
If they 16 is in inches, this would be 256 square inches per tile. That would cover 10,496 square inches. Divide by 144 and you get 72.89 square feet.
Assuming you mean 16x16 inches tiles... 441 tiles would cover the area exactly
Assuming you mean 18 inch tiles... 290 square feet is 41,760 square inches. Each tile is 324 square inches - so you would need 129 tiles in total (with a fraction of a tile left over)
You may want to use a calculator. 18 in x 18 in =? square inches There are 144 square inches in a square foot. Divide the square inches in one tile by 144. That should equal about 2.25 square feet per tile. 425 divided by the square feet in one tile -- that would give you the number of tiles. It would take about 189 tiles.
You would need 137 (136.23) 16" x 16" tiles to cover 22.5 square meters.
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.
Assuming the tiles are 16 inches square:200 square feet = 200 x 12 x 12 = 28,800 square inches.The tiles are 16 x 16 = 256 square inches.28,800 / 256 = 112.5So you would need a minimum of 113 tiles, not allowing for any that would need cutting at the edges of the room.
