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.
A rectangular floor can be completely covered by 3x3 ft tiles or 5x5 ft tiles if its dimensions are multiples of both tile sizes. Specifically, the area of the floor must be a common multiple of the areas of the tiles, which are 9 square feet and 25 square feet, respectively. The least common multiple (LCM) of 9 and 25 is 225, indicating that the total area of the floor should be a multiple of 225 square feet. Thus, possible dimensions could include any rectangle with an area of 225, 450, 675 square feet, etc., as long as the length and width are compatible with the tile sizes.

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.
