Not enough dimensions to tell.
20*20 square feet tile = 400 square feet, so in principle, two tiles will cover 800 square feet, which is more than enough. This is provided that the offcuts can be used.
If you buy 18 boxes you will have enough, plus a few extra. 18 boxes will cover just over 434 square feet.
It is not clear what is meant by an "18x18 square feet" tile. 18ft * 18 ft = 324 square feet, so that one tile will be more than enough. An 18 inch by 18 inch tile cannot be a 18x18 square feet tile.
