Simple. 18"x18" = 324 inch². One Square foot (12"x12") is 144 inch². So, take your 140 ft² and multiple it by 144 that converts your square foot requirement to square inch requirement. 140x144 = 20,160 inch². Divide 20,160 (your inch² area) by 324 (the area each tile covers) and you get 62.22 tiles. Now, you need to factor in waste, that is the partial tile, cuts, and damage that will be thrown away. Normally, figure 10-15% based on the configuration of the area. If you are intalling in a kitchen that has pantries and refrigerator cutouts, that will increase your waste. If you are tiling a square room, it will likely be less.

20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
There are 30.48 centimetres in one foot. Therefore, 140 feet is equal to 140 x 30.48 = 4267.2 centimetres.
11 and 2/3
You will need 140 tiles (10 x 14 = 140)

20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
A 24x24 inch tile would be four square feet. 140 divided by 4 would be 35 tiles.
140 centimeters = 4.59 feet.

There are 3 feet in one yard. Therefore, 140 feet is equal to 140/3 = 46.6 recurring (that is, 46.6666...) yards.
There are 3 feet in one yard. Therefore, 140 feet is equal to 140/3 = 46 remainder 2 or 46 yards 2 feet.
comes out to about 126 tiles, but would get 140 depending on amount of cuts there are and can always take the extras back.
64 tiles for a square shape of 140 square feet each tile equals 18 in x 18 in = 324 sq in 140 sq ft = 140 x (12x12) = 20160 sq in 20160 sq in : 324 sq in = 62.222 tiles sq root of 62.222 = 7.888 tiles per side so you will use 8 tiles per side and will have a leftover of .112
There are 30.48 centimetres in one foot. Therefore, 140 feet is equal to 140 x 30.48 = 4267.2 centimetres.
