A 30ft X 30ft roof would be 9 squares

3 bundles makes one sq

I assume your talking about Roofing? It takes me one box for 20- 25 squares of shingles. (Thats if you put the nails where they go, and dont leave any out)!
A 'bundle' is an arbitrary amount - Usually we talk about 'squares' in roofing. One 'square' is 100 square feet
There are 9,455 squares. All you need to do is add all of the square numbers up to 30, and you'll get you answer.

There is 100 sq ft to one square. So, you will need 10 squares.

There are approximately 250 nails to a roofing coil. When you buy them in a case they typically have around 7200 nails total. Hope that helps!
The question cannot be answered for two reasons:There are no units for the "30x30" in the question."30x30" suggests an area, a 2-dimensional measure rather than a length, such as a yard.
Roofing shingles are measured in "squares". One square is 100 square feet. *ASSUMING YOUR ROOF IS FLAT OR NEARLY FLAT* 16' x 80' = 1280 square feet. You'll need 12.8 (or 13) squares of roofing shingles. The majority of roofing shingle bundles are 3 bundles per square. 13 squares times 3 bundles per square = 39 bundles (minimum). Good luck!
Seriously ?... 900 !
