240 square tiles are needed
that question depends on how big your tiles are and how big your floor is
6' x 9' (54 square feet) = 6 square yards of tiles needed.
it would be 81 tiles
If the floor tiles are measured in inches and the room is measured in feet then the tiles are 1sq feet and the room is 6x8 = 48 sq feet so you would need 48 tiles.
It should take about 825 1 foot square tiles to cover a floor with those dimensions. This assumes roughly a 10% waste factor.
