To determine the number of tiles needed for a 15x5 room, first calculate the area of the room, which is 15 feet x 5 feet = 75 square feet. The number of tiles required will depend on the size of each tile. For example, if each tile is 1 square foot, you would need 75 tiles; if each tile is 2 square feet, you would need 37.5 tiles, which rounds up to 38 tiles.
You will need 233 30x30cm tiles to cover the room.

To calculate the number of 18x18 ceramic tiles needed for a 12x12 room, first determine the area of the room and the area of one tile. The area of the room is 144 square feet (12x12), and the area of one tile is 2.25 square feet (1.5x1.5). Dividing the room area by the tile area, you'll need about 64 tiles (144 ÷ 2.25). It's advisable to purchase a few extra tiles to account for cuts and breakage.

You will need 233 30x30cm tiles to cover the room.
The answer will depend on the size of the tiles!
123 tiles
16 square tiles
You would need a total of 36 tiles to cover that area.
I assume you mean an 8ft x 6ft room, which is 48ft2. I assume you mean 12in x 12in tiles, which are 1ft2 tiles. I don't know how many tiles are in a box, but you would need 48 12in x 12in tiles.
That would depend on the size of the tiles.
13 boxes with 13 tiles in each

24 of them.
You would need 56 tiles to do the floor
