Super fine 40-gauge copper wire has a diameter of only 0.080mm and weighs only 44.5/gkm . Suppose a spool of 40-gauge wire weighs 600.g less after some wire is pulled off to wind a magnet. How could you calculate how much wire was used?

Diameter of the wire = 0.080 mm

Weight of wire per km = 44.5g  

Weight of wire used to wind a magnet = 600 g

Therefore, length of the wire used:

600 g x 1 km/ 44.5g = 13.48 km

The length of the wire used was 13.48 km .

The length of  wire that was used is 13.48km

You could  calculate how much wire was used by dividing the wire weight  in g by the wire  weight in per gkm

Length of wire used =Weight of wire in g/

Weight of wire per gkm

Let plug in the formula

Length of wire used=600.g/44.5/gkm

Length of wire used=13.48km

Inconclusion The length of  wire that was used is 13.48km
