...If you click on the "Advanced" box in the upper left/center of SE, you'll open a coil and wire "dimensions" box that includes surface area... among other things. Play around with it and see what you come up with.

I really appreciate you taking the time to write the SE blog So'F! I have some light reading I can do now!
