You need 225 tiles. :)
144 tile assuming you have no waste.

224*12*12= 32256 32256/169=190.87 you need minimum 191 13x13 tiles
each tile is 1 sq ft and room is 6x5=30 sq ft so you need 30tiles
each tile is one square foot so you need 55 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.
224*12*12= 32256 32256/169=190.87 you need minimum 191 13x13 tiles
each tile is 1 sq ft and room is 6x5=30 sq ft so you need 30tiles
each tile is one square foot so you need 55 tiles
each tile 12 x 12 inch = 1 sq ft 11 x 11 foot room = 121 sq feet you need 121 tiles
144 or 1, depending on if '12 x 12' is in inches (assumed) or feet (one really big tile!).

One 12 ft x 12 ft tile will be more than big enough!
To determine the number of 12 square tiles that fit into a 350 sq ft room, divide the total area of the room by the area of one tile. In this case, the area of one tile is 12 sq ft. Therefore, 350 sq ft divided by 12 sq ft equals approximately 29.2 tiles. Since you cannot have a fraction of a tile, you would need to round the number down to 29 tiles.
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.
