Area of a 3 in * 6 in tile = 18 sq inches.
Area to be covered = 10 sq feet = 10*144 sq inches = 1440 sq inches.
Therefore, minimum number of tiles required = 1440/18 = 80 tiles.
That is the mathematical answer. In real life the number of tiles required will depend on the shape of the area to be covered and, possibly, its exact dimensions. It will depend on the extent to which offcuts can be used and on breakages.
