It depends on the size of the tiles and also, to some extent, on the shape of the area that you need to cover.
15 tiles exactly.
12 inches = 1 foot Thus the tiles would be 1 foot square. You therefore need 30 to cover a 30 square foot room.
A 12x12 tile covers 1 square foot (since 12 inches = 1 foot). To cover a 144 square foot area, you would need 144 tiles, as each tile covers 1 square foot. Therefore, you need a total of 144 tiles to completely cover the area.
144
18..
64 nos tiles is required calculation is
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)
1080 will be your answer
Assuming that 12 x 12 is 12" x 12" (one square foot), then 30 one-square-foot tiles would cover 30 square feet.
1 tile = 1.77 of a square foot, 240 Sq.Ft. divided by 1.77 = 135.5 tiles ok
234
Well if 12x12 is one square foot and you have 44 you need to cover figure 10% for breakage (5 tiles) it looks like 50 tiles will do ya
