Assuming that the size refers to 24 INCHES by 24 INCHES, each paver will cover
2 ft * 2 ft = 4 sq ft
So, to cover 120 sq ft will require 120/4 = 30 pavers.
This also assumes that the shape that is to be covered is "well behaved" and that all offcuts can be used. In that respect, it is a mathematical answer. For real life, depending on your skill level go for 5-10% more pavers.
Tiles that are two feet on a side cover 4 square feet. 378 of them cover 1512 square feet.
144.63 pavers
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
If each paver is 6 x 3 then it has an area of 18 square feet. You will need exactly 25 of these to cover an area of 450 square feet.

24x24 inches is two feet by two feet. 2x2 is four square feet.
4.5 pavers will cover 1 sq foot. So 4.5 x 360 =1620 pavers
If each paver is 6 x 3 then it has an area of 18 square feet. You will need exactly 25 of these to cover an area of 450 square feet.
It will take four pavers to cover one square foot. You will need 720 pavers.

How many 24x24 tiles it take to cover a 14×14 room
you would need 10 pavers to cover this area if the pavers are 1x1 ..most pavers are not this large they are usually 2x4. I would recommend buying a couple of extra pavers so that you can have cuts instead of all the pavers being the same size.
18" is 1.5', so we can discover the number of square feet in one paver by multiplying 1.5 x 1.5 = 2.25 square feet. To fill an area of 14' x 14', or 196 square feet, you would need 196 / 2.25 = 87 pavers, with room for .11 pavers left over. So to cover it completely, 88 pavers would do the trick.
