To calculate the number of square tiles that you need to cover the room, use this formula:
Number of tiles = Area of the room in square foot/area of a single tile in square foot.
So if for example the dimension of your room is12 x 12, the area would be equal to 144 square feet. So if the tile's dimension is 18 x 18(inches), its area = 324 square inches, convert it to feet.
144 square inches = 1 foot
324 inches = 324/144 = 2.25 square feet
So use the formula mentioned above to find out the number of tiles:
To calculate the number of square tiles that you need to cover the room, use this formula:
Number of tiles = Area of the room in square foot/area of a single tile in square foot.
Number of tiles = 144/2.25 = 64
So you need 64 tiles to cover your room
Note: You can simply substitute the dimensions of your room to this solution.
