If a surface is 144 square feet = 20,736 sq inches, you need at least (172,8 rounded to) 173 tiles (6 by 20 inches) to cover it.
Each tile is 6 inch*20inch= 120 sq inch. 20,736 sq inch / 120 sq inch = 172,8.
Depending on the shape of the surface you may need more if you have to cut some tiles to make them fit.

How many 20x20 porcelain floor tiles do you need for 660sf?
You will need 250 tiles. First, you must calculate how many square feet there are in each tile: 20" X 20" = 400 square inches per tile. One square foot = 144 square inches (12" X 12" = 144 square inches) So, 400 square inches per tile divided by 144 square inches per foot = 2.778. That means there are 2.778 square feet per tile. Now you can calculate how many tiles you need to cover 660 square feet: 660 square feet divided by 2.778 square feet per tile = 237.58 tiles. However, in practice, you will also need about 5% for waste (cuts, breakage or defective tiles) - so add that amount: 237.58 X 1.05 = 249.46 tiles. Round up, and you will need at least 250 tiles. If you're doing a patterned design or laying tiles on the diagonal, you'll want to increase your waste factor a little bit. Typically, folks will just round pieces up to the next full box of tiles.
