    Thank you
    We need to know the density of the material the wire is made from. If the length is l, the volume is l x the cross section (use pi r squared).

    Knowing the density, you can then have an equation in l, using density = weight divided by volume.

    Post #2 tells you what to do. In particular, it tells you that the density is required before the calculation can be done.

    Get the density and do what post #2 says. If you are stuck, show all your work and say where you are stuck.

    Here you go, Metals and Alloys - Densities

    Let us know if you need help with teh calculation, but have a go yourself first, eh?
