20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
20X20" tiles are 1.67'X1.67' giving a total sq ft per tile of 2.8 s/f 100 tiles would cover 280 sq feet so looks like 97 tiles gets you to 272. we always recommend about 5-7% overage to allow for a broken tile or a bad cut.
Without allowing for any waste, you would need 78 tile.
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
12 X 12 = 144 inches = 1 Square Foot of tile 165 X 144 = 23760 20 X 20 = 400 23760 / 400 = 60 tiles
comes out to about 126 tiles, but would get 140 depending on amount of cuts there are and can always take the extras back.
20" = 2.78 square feet. Now divide the area of the tiles into the area of the room. 140/2.78 = 51 tiles
If that is 60" tiles it would take 16 total.

1,000 tiles.
Assuming they're the perfect shape and you dont lose some to the dimensions, 20*20 inches is 400in2, this is 2.77777778ft2. 7000/2.77777778 is 2520 tiles
1070 square feet is 154080 square inches. (1 square foot is 12x12 or 144 square inches.)a 20x20 inch tile is 400 square inches.So the question could be restated as "how many 400 square inch tiles does it take to cover 154080 square inches?"154080 / 400 = 385.2
Assuming they are 20 by 20 inches, then the area of a tile is 400 feet2/144. 200 feet2/(400 feet2/144) = 72
12 X 12 = 144 inches = 1 Square Foot of tile 165 X 144 = 23760 20 X 20 = 400 23760 / 400 = 60 tiles
440 sq feet = 440 x 144 sq inchesanswer = 440 x 144/ (20 x 20) = 440 x 144 /400 = 1.1 x 144 = 158.4 tiles ~ 159 tiles
250 tiles
