L is length;
If 0.2 cm "thickness" means "diameter, then volume is
or cubic centimeters.
Now you need to use the density for copper. You find that yourself and use it. You are given, 1 kilogram of copper.
--
If your reference source tells 8.96 grams per cubic centimeter is density for copper then you have what you need.
You were given 1 kilogram of copper, which is 1000 grams of copper.
SOLVE FOR L.
