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)
12 X 12 = 144 inches = 1 Square Foot of tile 165 X 144 = 23760 20 X 20 = 400 23760 / 400 = 60 tiles

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
12 " x 12 " = 1 foot by 1 foot = 1 sq foot. 900 / 1 = 900 tiles are needed (plus waste).
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.
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
