24x24=4sq ft. 720/4=180.
4 sq ft
If the measurement 24x24 is in feet, then the room is 576 sq feet in area
I assume the measurement is in inches (it would have been helpful to say, because the measurement is vital!). So these are 2ft x2ft=4sq ft. 120 sq ft divided by 4 sq ft is 30 tiles. If the shape of the 120 sq ft is something odd like 7.5ft x 16ft etc there is a lot of awkward cutting to do, and in some cases there will be wastage, so think ahead, you may need more.

Assumption 1: The question refers to 24 inch * 24 inch tiles. Assumption 2: All off-cuts are used. A 24" by 24" tile is 2' by 2' so that it covers 4 square feet. Number of tiles required = 260 sq feet / 4 sq ft = 65.
It depends on the units used for 18 by 18. For example, two tiles of 18 ft x 18 ft will be enough. On the other hand, you will need just over 1000 tiles measuring 18 cm x 18 cm.
6,144 tiles !
204 tiles
Just multiply 20 by 20 to find that each tile has 400 square feet to it. Then divide 1000 by 400 to find that you'll need 2.5 tiles -- so you should buy three.
