12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240
A square with 6" on each side is 1/4 sq ft, so there are 4 tiles in 1 sq ft, and 4 tiles x 8 = 32 tiles.
You will need 140 tiles (10 x 14 = 140)
A 12*12 sq inch tile has an area of 1 square foot. So, to cover 20 sq ft you will require a minimum of 20 tiles. I say "minimum" because the actual number depends on the shape of the area to be covered and whether or not all offcuts can be used.

To find out how many 20-inch tiles you will need to cover 100 sq ft, you first need to calculate the area of one tile. A 20-inch square tile covers 20 x 20 = 400 sq inches. Since 1 sq ft = 144 sq inches, you divide 400 by 144 to get approximately 2.78, meaning it will take about 2.78 tiles to cover 1 sq ft. Therefore, to cover 100 sq ft, you will need about 278 tiles.
12X20 = 240 sq feet 12"x12" tiles are 1 sq foot each so must be 240/1= 240
A square with 6" on each side is 1/4 sq ft, so there are 4 tiles in 1 sq ft, and 4 tiles x 8 = 32 tiles.
There would be 4 of the 1/2" tiles in each sq inch since 12"x12" = one sq ft There are 144 sq inches in a sq foot

You will need 140 tiles (10 x 14 = 140)
one 12 x 12 tile is one sq ft you need 480/1 = 480 tiles
12 X 12 = 144 inches = 1 Square Foot of tile 165 X 144 = 23760 20 X 20 = 400 23760 / 400 = 60 tiles
A 12*12 sq inch tile has an area of 1 square foot. So, to cover 20 sq ft you will require a minimum of 20 tiles. I say "minimum" because the actual number depends on the shape of the area to be covered and whether or not all offcuts can be used.
12 " x 12 " = 1 foot by 1 foot = 1 sq foot. 900 / 1 = 900 tiles are needed (plus waste).
Assuming the tiles are 6" x 20", the area of 1 tile = 1/2 x (1 and 2/3) = 1/2 x 5/3 square feet which is 5/6 square feet. To cover 1800 sq ft, the number of tiles required is 1800 / (5/6) = 1800 x 6/5 = 360 x 6 = 2160
