Assuming that you are asking about a rectangular or square tile, the answer is one--Squares are rectangles with sides of equal lenght.
A rectangle made up of 48 square tiles has an area of 48 square units, whatever the units of each tile are (if they are one-inch-square tiles or one-foot-square tiles, etc.) Let's say that the area is made up of 48 one-foot-square tiles. Then the area is 48 square feet. To find the area of a rectangle, you multiply the length times the width. So, A = L x W, and we know that A = 48. What two numbers can you multiply to get 48? 2 and 24, 3 and 16, 4 and 12, and 6 and 8. So you could have four different size rectangles that cover 48 square feet. The dimensions are: 2 feet by 24 feet 3 feet by 16 feet 4 feet by 12 feet 6 feet by 8 feet
One square foot is 12 inches by 12 inches so you can fit in it 9 tiles in a 3 tiles by 3 tiles square.

405 inches
in a square/rectangular room, count the tiles across and the tiles along then multiply.
It should take about 825 1 foot square tiles to cover a floor with those dimensions. This assumes roughly a 10% waste factor.
Add 8 plus 6 and you have your answer. You need to use four and arrange them so that the long side is against a short side, sort of like laying paving stones.. * * * * * Unfortunately, that will give a herring bone pattern, not a square. The smallest square has sides which are the least common multiple of 6 cm and 8 cm, that is, 24 cm.

If you are not allowd to cut any and you can disregard the width of the grout between the tiles: 125x = 55y , x and y are integers 5*25x = 5*11y 11*5*25 = 25*11*5 = 1375 A square 13.75 meters on each side using 275 tiles
The smallest size would be 15x15 feet which is 225 feet2. That is 9, 5x5 feet tiles. Or it is 25, 3x3 feet tiles.
I recall answering this recently. If the area is square, and the tile dimensions are in inches then the tiles are 4 sq ft and you need 12 tiles. If the area is not square (Circular? Long and thin?) then you will have wastage, so you will need more tiles.
The number of 13 inch tiles needed will depend on the actual dimensions of the floor rather than the square footage. If the room is square, 169 tiles, with 1/16 inch or larger grouted seams, will completely cover it. If the floor is rectangular, additional tiles will be needed, the exact number depending on how many tiles must be cut. As a general rule, approximately 10 percent extra is usually sufficient to cover waste from cutting and accidental breakage.
