If the area is a rectangle which is 6 inches or 1 ft wide, or if you can use all of the off-cuts, then 52 tiles will suffice. The two rectangles above are quite narrow and unlikely in real life. In all other cases, you will require more tiles: how many more will depend on the exact shape and your tiling skills. For example, if you are unable (or unwilling) to end up with a mosaic effect, a 4 inch wide strip will require 78 tiles.
4 = 1 square ft
4 x 13 = 52
1296
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.
40 square feet = 40*12*12 square inches = 5760 sq inches No of 16*16 tiles = 5760/(16*16) = 22.5. So 23 tiles will do. BUT if this is a practical question rather than a maths question, you will also need to allow for wastage.
9 tiles, but you would have to cut a lot off 5 of them.

You will need at least 66,828 1/4 tiles to cover that area.
Each tile will cover 100 square inches. 12,000 square feet is 1,728,000 square inches. You will need 17,280 tiles.
If the tiles are 12x12 inches square - you would need... 75 !
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.
Assuming you mean the tiles are 16 inches square - you would need 169 tiles.
If your tiles are 12 inches x 12 inches you would need 144 of them.
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 would need 137 (136.23) 16" x 16" tiles to cover 22.5 square meters.
You will need approximately 23.4 tiles, so 24 tiles. Assuming 13x13 tiles is in inches.
You will need 250 tiles. First, you must calculate how many square feet there are in each tile: 20" X 20" = 400 square inches per tile. One square foot = 144 square inches (12" X 12" = 144 square inches) So, 400 square inches per tile divided by 144 square inches per foot = 2.778. That means there are 2.778 square feet per tile. Now you can calculate how many tiles you need to cover 660 square feet: 660 square feet divided by 2.778 square feet per tile = 237.58 tiles. However, in practice, you will also need about 5% for waste (cuts, breakage or defective tiles) - so add that amount: 237.58 X 1.05 = 249.46 tiles. Round up, and you will need at least 250 tiles. If you're doing a patterned design or laying tiles on the diagonal, you'll want to increase your waste factor a little bit. Typically, folks will just round pieces up to the next full box of tiles.
An area of 50 square feet requires a minimum of four 48-inch tiles.
