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.
To determine how many 18x18 inch tiles are needed for a 42 square foot bathroom, first convert the tile size to square feet. An 18x18 inch tile is 1.5 feet by 1.5 feet, which equals 2.25 square feet per tile. Then, divide the total bathroom area (42 square feet) by the area of one tile (2.25 square feet): 42 ÷ 2.25 = 18.67. Since you can't use a fraction of a tile, you would need 19 tiles to cover the bathroom.
