How it is calculated
The area to tile (length × width) is divided by the area of one tile. Tile sizes are entered in inches, so the tile area is divided by 144 to convert it to square feet.
An extra percentage is added for tiles that are cut at the edges, broken or set aside for future repairs. The result is rounded up to whole tiles and whole boxes.
