Question:

how many 18x18 tiles do i need in an area of 198 sq. ft?

is it correct if i divide 198 by 2.25= 88 tiles? help ty

Answer:

You are correct, but only if you don't have to cut any tiles and the area you're tiling is basically one big rectangle with nothing in it like counters or appliances. If you have to cut tiles, the general rule of thumb is to multiply by 125%. In your case, that would be 110 tiles -- and bear in mind that general rule doesn't always work.
88 tiles is correct .. But the highest I d ever do to figure scrap is 10% and thats high. 10% of 198 is 19.8 s/f round off to 20 s/f. 20 s/f divided by 2.25 s/f is 8.88 tile or 9 tile. Most I would get 97 tile. But tile is some times sold by the whole carton so figure that into the equation. Any questions you can e mail me through my avatar and check my qualifications there. GL
What's the dimensions for the tiles? Cm? M? Km? mm?
