How many 24x24 tiles needed for 120 sq ft?

Answer 1

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.
