Best Answer

18 inches = 1.5 feet

18" x 18" = 2.25 square feet

100/2.25 = 444/9 tiles

It's recommended that you have 45 of them on hand.

The perimeter of a square is 100 inches. How many square tiles 1 inch on each edge are needed to cover its area?

Find out how many square feet you need, and multiply that number by four. For example: If your room measured 10 feet by 10 feet, you need 100 square feet. For 6 inch tile, multiply that by four and you find you'll need 400 tile.

One side of a square is 10 inches long. How many one square inch tiles are needed to cover its area?

Without any waste you would need 25 tiles.

10" * 13" = 130 sq inches = 130/144 = 0.9028 sq ft. Area to be covered = 100 square feet so tiles required = 100/0.9028 = 110.77 tiles ie 118 tiles. That is the mathematical answer. In real life, though, the answer will also depend on how "well behaved" the area to be covered is. If it has lots of awkward corners or curves, you will need to cut more tiles to shape and, unless you are able to use all such offcuts, you will require more tiles.
