The remaining uncertainty can be reduced by a [insert your favorite useless education here] student, ...

...weighting them (and a few individual nails). You don't want to wait until he counted them, right?

How many nails are in the picture?

800-900.

How did you arrive at this solution?

That looks like about 5 pounds of 2" common nails, so 800-900 nails, depending on the manufacturer.

Let N be the number of nails ,

V be the average volume of the nail bulk, and u be the average volume of a single nail (at different orientations). Let l be the length of a single nail. Exclude the empty spaces between the nails!

Identify the average shape of the nail bulk. Find u with respect to l (I.e. u = f(l) ). Find V with respect to l (I.e. V = g(l) ).

Now Nu = V, so N = (V/u) = g(l)/f(l)
