I was at a doctor's office a month ago, and after they took my height, weight, blood pressure, mother's maiden name and fingernail salinity, they came back in a couple of minutes and handed me a little print-out of all these fact-like bits plus some extra -- including my surface area.
I haven't run the numbers but I'll just bet the software that calculated that number was based on the assumption I was of uniform density roughly equal to water, and spherical. Also, WTH? Why figure it? Why tell me? To make providing a hospital gown simpler? So I know how much suntan lotion to buy? What? --It's probably required somewhere in ACA-Obamacare. It sounds like something Congress would want.
