1. The problem statement, all variables and given/known data The diameter of metal wire is often referred to by its American wire-gauge number. A 16-gauge wire has a diameter of 0.05082 in. What length of wire, in meters, is found in a 1.00-lb spool of 16-gauge copper wire? The density of copper is 8.92g/cm3. 2. Relevant equations 3. The attempt at a solution I just can't get the last step. I currently have it set up as, (1lb)x(453.592g/1lb)x(1cm^3/8.92g)x(1in^3/16.387cm^3)x... I know I need to get from inches cubed to meters. But how do I go from something cubic to linear? Thanks for the time!
