30 tiles! But you'll need more than 30 tiles to cover wastage, breakage, etc.
To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.
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.
18" x 18" = 1.5' x 1.5' = 2.25 square feet90/2.25 = 40 tiles.
