How many 18x18inch tiles will you need to cover 800 sq ft?

Answer 1

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
