Bacteria on your skin

Writer Dorion Sagan and biologist Lynn Margulis write in their book, Garden of Microbial Delights, that “human skin harbors some 100,000 microbes per square centimeter”. Use this to estimate the mass of the bacteria living on your skin. Be sure to clearly state your assumptions and how you came to the numbers you estimated, since grading on this problem will be mostly based on your reasoning, not on your answer.
