**Reiny**, Thursday, October 14, 2010 at 11:53amI don't like this question.

There is simple purely mathematical solution

volume of 1 disc = π(2^2)(.1) = .4π cm^3

so number of discs = 1000/(.4π) or 795.8

so they can make 795 discs

Logistically, this is a very ambiguous question

- is the 1000 cm^3 in a block of metal or in sheets?

- are the discs manufactured by pouring liquid metal into a mould ?

- are they stamped ? If so, is the scrap metal used again?

- arhhh! ....
