To cover 720 sq feet of floor with 18" x 18" tile, you would need 320 tiles.
18 in/12 in/ft = 1.5 feet 1.5 x 1.5 = 2.25 sq ft per tile 130 sq ft/2.25 sg ft/tile = 58 tiles
120
In order to answer this question, we need to convert the dimensions of the tiles into ft. This makes all units consistent, and so easier to work with. There are 12 inches in a foot, and so to convert from inches to feet you need to divide by 12. In this case the tiles are 18x18, so divide this by 12 and you get 1.5ft x 1.5ft This means the tiles have an area of 2.25 sq ft. To find how many are needed for 800 sq ft, you just divide: 800/2.25 = 355.555555... Therefore, you would need 355.5 recurring tiles to cover the whole area.
Each 24x24 tile is 2 sq ft. You need 60 tiles minimum.
The answer will depend on the units used for measuring the tiles. Two 8 ft x 8 ft tiles, for example, would be big enough.
