What kind of tiles? For the floor or walls also? Simplest example. 12x12 floor tiles. 10x12 room. One length times one width. 10x12=120 12x20 room, 240 tiles. 6x6 tiles there are 4 tiles in each square foot of floor space 10x12x4=480 Whatever you are doing, one length times one width gives you the square footage. Then figure how much each tile covers and multiply.

You would need 111 tile, but with waste you will want to get 125 tile.

You would need 56 tiles to do the floor

You need 225 tiles. :)

each tile is one square foot so you need 55 tiles

The tile is bigger than the area that you want to cover (12x12 > 10x11) so one tile will do. <><><><><> However, if you meant 12x12 INCH tiles, and a 10x11 FOOT room, you would need 110 tiles.

That depends entirely on the SIZE of the tiles ! A tile size of 1 ft2 would need 112 tiles, whereas a tile size of 6in2 would need 448 !

Each tile will cover 2 square feet. So you will need 12.5 tiles.

The size of a tile requires two measures. It is also necessary to specify the units used for both, the measure of the tile as well as of the room.

You will need approx 130 sq ft of tiles. Divide the tile dimension into the total to figure out the quantity. Allow for breakage/spoilage. Tile squares come in many sizes.

About 137 tiles, if they are 1ft X 1ft dimension, or about 137 square feet of tile. If you are using smaller tile, calculate how many tile are needed per square foot and multiply that times 137.

You need about 310 to 325 12x12 ceramic tiles for a 320 sq-ft room. Many tile dealers let you return unused tile. If your dealer does this, you should over-buy. You will probably break some, and the joint spacing may have an effect on the number of tiles required.
