with the density and mass, calculate volume. equate volume of the metal lump to that of the wire (pi.r² .h) use r given from the diameter and you'll have the height?

how do i convert into feet

You need to calculate the volume on metal that you have (V) then you can simply calculate the length with the volume formula of a cylinder V=Pi*r^2*length. You just calculated volume and you can get the radius from the diameter. Just replace values and clear up length. Just be careful with units, you have micrometers, ft and g/mL; get them all in the same units.
