Area of tile = 20 in x 20 in = 5/3 ft * 5/3 ft = 25/9 sq ft
Area to be covered = 12*24 = 288 sq ft
Minimum number of tiles required = 288/ (25/9) = 103.68 rounded up, that is 104.
In real life, you will need more. That will depend on how well behaved the shape is, the extent to which you can use offcuts and your skill level. You should allow 5-7% extra,
A 12x24 inch tile equals two square feet.
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
1,080 tiles exactly.
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
If you had absolutely no waste you would need 864 tiles. Since tile as large as 20" x 20" generally have a large amount of waste, make sure you add 10% into this number. With that you would need 950 tiles to complete your job.
A 12x24 inch tile equals two square feet.
If that is 60" tiles it would take 16 total.
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
1,080 tiles exactly.
You will need 44 six inch tiles to cover 11 square feet.
About 197 (196.875) 16" x 16" tiles will feet in that area.
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
Area of each tile = 20*20 sq inches = 400 sq inches. Area to be covered = 1744 sq ft = 1744*144 = 251136 sq inches. So minimum number of tiles required = 251136/400 = 627.8 is 628 tiles. That is the mathematical answer which assumes that almost all the offcuts can be used. If the area to be covered is odd shaped there will be a lot of offcuts that cannot be used unless you want a mosaic effect!
49 tiles will cover the are, with 1 inch strips spare
If you had absolutely no waste you would need 864 tiles. Since tile as large as 20" x 20" generally have a large amount of waste, make sure you add 10% into this number. With that you would need 950 tiles to complete your job.
Area of each tile = 20*20 = 400 sq inches. Area of room = 185*123 = 22755 sq inches. So minimum number of tile required = Roundup(22755/400) = 57. However, this number assumes that all offcuts are used and that there are no breakages. In real life neither assumption is realistic.
