How many 8x8 tiles do you need to cover 2915 sq ft?

Answer 1

8" X 8" is .67X.67 of a foot

so whip out the cell phone & do the multiplication that gives you about 1/2 of a square foot per tile...you do the math if you want the exact decimal

Then you divide the area to be covered by the area of the tile & that will tell you how many tiles

2915/(.67x.67) equals about 6500 tiles.

For a consumer or estimator you will need to think about grout joints (actual means you use less tile) and some allowance for waste & cutting & broken tiles, on a large open area 3-5% is plenty, on a cut up small offices or rooms 6-9% is a common allowance.
