One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
18 in x 18 in = 1.5 ft x 1.5 ft = 2.25 sq feet.
1.94 sq ft approx.
379.6875 ft2
6 x 24 inch tile = 144 sq in = 1 sq ft 400/1 = 400 tiles
One 18 inch x 18 inch tile = 1.5 ft x 1.5 ft = 2.25 sq ft.400 sq ft x 1 tile/2.25 sq ft = 177.77 = 178 tiles
18 in x 18 in = 1.5 ft x 1.5 ft = 2.25 sq feet.

18"x18"/144 sq inches per sq ft = 2.25 sq ft per tile for 18x18 tiles 900 sq ft / 2.25 sqft/tile = 400 tiles +10% for waste and cuts = 440 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
18 in = 1.5 ft (18 in)2 = (1.5ft)2 2.25 sq. ft. per tile 600 / 2.25 = 266 + 2/3 I do not know the shape of the 600 sq ft, so I would recommend buying a little extra, say 270-300 tiles.
Calculating how many tiles in a room· 12"X12" is DUH 144 sq inches & 1 sq foot· so multiply any tile size by its 2 dimensions ie 12X12 or 16X16 & that = the sq ft per tile.· 13"X13" is 169 sq inches divided by 144 sq inches in a sq foot =1.174 per tile· 18"X18" is 324 sq inches per tile divided by 144 sq inches per sq ft= 2.25 sq ft per tile· 20"x20" tiles are 2.778 per tile· 24X24 tiles are 4 sq ft per tileFormula would look like this(Tile L"x W"= sq inches)divided by 144 sq inches=sq ft per tile) room area divided by sq ft per tile= how many tilesSoooo once you know the sq feet you need, add a little for waste & breakage & ooops cuts & you will have enough..

18-in x 18-in = 324 sq in 324 sq in / 144 sq in per sq ft = 2.25 sq ft 2.25 sq ft / 9 sq ft per sq yd = 0.25 sq yd Answer = 0.25 sq yd
Simply divide the total area (384 sq ft) by the tile area (18 sq ft)384 / 18 = 21.333 tilesAssuming that you can only use a whole, and not .333 of a tile, you round up to the nearest tile.21.333 tiles --> 22 tiles
2.25 square feet
400.
