In order to answer this question, we need to convert the dimensions of the tiles into ft. This makes all units consistent, and so easier to work with. There are 12 inches in a foot, and so to convert from inches to feet you need to divide by 12. In this case the tiles are 18x18, so divide this by 12 and you get 1.5ft x 1.5ft This means the tiles have an area of 2.25 sq ft. To find how many are needed for 800 sq ft, you just divide: 800/2.25 = 355.555555... Therefore, you would need 355.5 recurring tiles to cover the whole area.

356 of them. Get 390 to be safe.

800 x 144 = 115,200 / 95 = 1,212 tiles. You might want to buy a few extras...

It depends on the units used to measure the tile: 12inch*24inch, 12cm*24cm or some other, unspecified unit.

20*20 square feet tile = 400 square feet, so in principle, two tiles will cover 800 square feet, which is more than enough. This is provided that the offcuts can be used.

800

Each tile covers 4 square feet. Which means you need 200 tiles to cover 800 square feet, plus spoilage.

If that is 2' x 4' it would cover 800 square feet. If it is 2" x 4" it would cover about 5.5 square feet.

convert inches to feet- 1.5- then divide into 800- 533.333333333333~ round up, and you need AT LEAST 534 tiles.. --------------------------------------------------------------------------------------- I do not think that the answer above is correct. 18" by 18" tiles measure 1.5 x 1.5 sq ft = 2.25 sq ft Then 800 divided by 2.25 = 355.55...(the 5 is recurring) sq ft, so the sensible answer is 356 tiles, but a few more should be added to allow for breakages

You would need 800 tile assuming you had no waste at all. Since this is unlikely you will need 825 tile.

8 square metres = 80 000 square centimetres (because a rectangle 8 m × 1 m would be 800 cm × 100 cm). 20 cm × 20 cm = 400 cm2. 80 000 / 400 = 200 tiles.

20*20 square feet tile = 400 square feet, so in principle, two tiles will cover 800 square feet, which is more than enough. This is provided that the offcuts can be used.
