yes I am getting the right answer for the length!

Sorry everyone, I forgot to post my efforts in solving the problem, so here I go again: The question says: Suppose you wish to fabricate a uniform wire out of 1.00 g of copper. If the wire is to have a resistance of R=0.500 Ohm, and a density of d=8920 kg/m3, and if all the copper is to be...
