443 square feet = 443*12*12 = 63792 sq inches
Each tile = 8*8 = 64 sq inches
So minimum number of tiles required = 63792/64 = 996.75 or 997.
However, that assumes that almost all the offcuts can be used. In real life it would be sensible to have more tiles to allow for breakages and wastage.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.
18 inch x 18 inch tile is really (1 and 1/2) feet by (1 and 1/2) feet That is (3/2) x(3/2) square feet = 9/4 square feet. To cover 900 square feet we need (900)/(9/4) = (900) x (4/9) = 100 x 4 = 400 tiles
It will cover an area of approximately 408.33 square feet.
5,184 2-square-inch tiles are needed.
440 6-inch square tiles.
