18 x18 is 1.5 ft x 1.5 ft = 2.25 sq ft
it depends exactly how they are laid out and how much cutting you do but the absoulute minimum amount of tiles will be 272 / 2.25 tiles = 120.8 tiles so you will need at least 121 tiles. However this would involve a lot of cutting.
depends on the actual dimensions of your floor/wall i would suggest you buy 140 tiles as this will cover an area of at least 21 ft by 15ft = 315 ft. It does however depend on the dimensions but 140 tiles seems the right amount
The diagonal of an 18x18 tile is 18*sqrt(2) = 25.46 units.
102.22 tiles because each tile is 2.25 sq.ft. 230 / 2.25 =102.22 so really 103 tiles.
One tile of size 13' by 13' will cover 169 square feet and so will be more than sufficient.
So each tile is 12" by 12" square, right? So each tile is ONE square foot? (a perfect square that's a foot long and a foot wide). Each tile is one square foot and you need to know how many add up to 400 square feet. I think the answer is the square root of Pi.
152 sq.ft. of tile will cover the floor, you need to account for waste and defects in the tile you should also planning on keeping some extra tiles once you are done, they are often discontinued and unable to find in the event one is damaged
144/2.25=64. 18x18 tile cover 2.25 sq ft area.
To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.
You would need 800 tile assuming you had no waste at all. Since this is unlikely you will need 825 tile.
160 of them.
The answer will depend on the units used for measuring the tiles which you have failed to specify.
if you are quoting inches, then a 18x18 tile measures 2.25 square feet. On that basis you would need 106.66 or 107 to the nearest.
2.25 square feet
18 in/12 in/ft = 1.5 feet 1.5 x 1.5 = 2.25 sq ft per tile 130 sq ft/2.25 sg ft/tile = 58 tiles
There are 2.25 square feet in 1 18" x 18" tile. Counting for NO waste, you would been 71 tile. Since tile this large with surely have some waste you will want to buy around 78 tile.
Depends on the size of the tile. Get the area of the tile and then divide by the area you need to fill.
The diagonal of an 18x18 tile is 18*sqrt(2) = 25.46 units.
