Q:

How many 12-by-12-inch patio pavers do you need to cover 120 square feet?

A:

At least 120 12-inch-by-12-inch patio pavers are needed to cover an area that is 120 square feet. The precise number may vary depending on the exact shape of the 120-square-foot area; additional pavers may be necessary if some pavers must be cut down to accommodate oddly shaped spaces.

Lowe's recommends adding a surplus of 5 to 10 percent to allow for possible breakage of pavers. This increases the minimum number for the 120-square-foot space to 126 to 132 pavers.

Lowe's also suggests beginning the patio project by digging the area to a depth of 7 inches, laying down landscape fabric, putting in a 4-inch layer of coarse gravel, and then topping it with a 1-inch layer of sand before installing the patio pavers. A 120-square-foot space would require 40 cubic feet of gravel and 13.3 cubic feet of sand.

    A:

    In order to cover an area of 360 square feet, the minimum number of tiles needed is 360 tiles. Since the tile size of 12 inches by 12 inches is equivalent to 1 foot by 1 foot, the area of one tile is 1 square foot. Dividing 360 square feet by 1 square foot equals 360 tiles.
