Get a thousand, just in case.
1080 will be your answer
It depends on the size of the tiles and also, to some extent, on the shape of the area that you need to cover.
A tile measuring 2 foot by two foot (which, incidentally, is an unusually large tile) has an area of 4 square feet, so it would take 100 such tiles to cover a 400 square foot floor.
It should take about 825 1 foot square tiles to cover a floor with those dimensions. This assumes roughly a 10% waste factor.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
Depends on how big the tiles are.
Multiply the length by the width. To find the minimum number of tiles to cover an area, divide the total area by the area of one tile. (This is straightforward when tiles are 1 foot square.)
1,080 tiles exactly.
109 You need 98 tiles to cover the area and then 10% extra for waste.
15 tiles exactly.
If the tiles measure 12 inches square then the area of each tile is 1 sq foot. Therefore 1400 tiles are needed to cover an area of 1400 square feet. However, the actual dimensions of the area being tiled can affect the number of tiles required so closer examination is needed.
If the tiles are 1 x 1 FOOT, then they cover 118 square feet.If the tiles are 1 x 1 INCH, then they cover (118/144) = 0.8194 square foot (rounded)If the tiles are 1 x 1 METER, then they cover (118 x 3.280842) = 1,270.1 square feet (rounded)
