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.
6' x 9' (54 square feet) = 6 square yards of tiles needed.

To determine how many 18x18 inch tiles you need for 56 square feet, first convert the tile size to square feet. An 18x18 inch tile is 1.5x1.5 feet, which equals 2.25 square feet per tile. Next, divide the total area needed (56 sq ft) by the area of one tile (2.25 sq ft): 56 ÷ 2.25 ≈ 24.89. Therefore, you will need 25 tiles to cover 56 square feet.
100 tiles or 96 which is the correct amount
102.22 tiles because each tile is 2.25 sq.ft. 230 / 2.25 =102.22 so really 103 tiles.
