2. [#142] How many cells are you?How many cells in a human? Assume that cells have a typical size of about 10 µm (1µm = 10-6 m) in all directions.And that we are the same density as water, and are made completely of cells (both exaggerations, of course, butfine for an order of magnitude estimate).Hints: What is the volume of a cell? What is the volume of a human? How can these quantities be related to give thenumber of cells in your body? The shape of the cell is not important in this rough estimate: for instance, thedifference in volume fraction between say cubes and close packed spheres is only 26%.Format: When you enter your answer, enter it as a power of 10. For example: for 100000, enter "10^5". We'll usethis notation later, too.
