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.
Assuming the tiles are 1 foot squares, you would need 10*15 = 150 tiles.
104.0625 tiles exactly (so - 105 tiles in all)
7.35 Is what you need
16 square tiles
each tile is one square foot so you need 55 tiles
You would need 56 tiles to do the floor
123 tiles
400. That's because there are four six-by-six tiles in each square foot. 4 tiles per square foot X 100 square feet = 400 tiles.
342 of them.
Each tile will cover 2 square feet. So you will need 12.5 tiles.
24 of them.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
776. You need four tiles for one square foot (tiles are 36 square inches, a square foot is 144 square inches) so 4 tiles times 194 sqft is 776. You will want some spares too.
100
75 tiles would do it (a 12*12 inch time = 1 square foot) but you need 10% over this for waste so you need to get 83 tiles.
