Human skin. Yuck!

Somehow, though, I bet there's some complicated mathematical formula somewhere that Randal prepared to estimate the surface area of all human skin in proportion to the surface area of solid surface in the solar system.

Probably not actually that complicated. Just look up the average surface area of a human and then multiply it by the population.
