Best Answer

60 square feet = 60*12*12 = sq inches.

Therefore, minimum number of tiles required = 60*12*12/(18*18) = 26.66...

ie 27 tiles.

That is the classroom answer to the mathematical question. However, in real life, the area to be covered may not be of a shape in which whole tiles can be used. In that case, unless you can use all the offcuts you will require more tiles.
