A 16 Gauge wire has a diameter of 0.0508 inch. Calculate the length in meters of a 5.00 pound spool of this wire. The density of copper is 8.92g cm^-3

Answer 1

since the cross-section area is

pi/4 d^2 = 0.002027 in^2 = 0.0131 cm^2, we have

5lb * 453.6g/lb * 1cm^3/8.92g / .0131cm^2 = 19409cm ≈ 194m
