How large is humankind in volume?
It seems from Wolfram Alpha that the average human volume is around 66.4 liters. The current human population is 6.93 billion people.
Therefore all humankind is 4.602 * 10^11 liters of stuff, which correspond to a cube with a side of 772 meters or a sphere with slightly less than 1 km diameter.
This roughly corresponds to a small asteroid. Wolfram Alpha tells us that it's 0.92 times the water in the Sydney Harbour, but it hardly seems suggestive to me, perhaps because I'm not Australian. We would be barely a blip on a map of the planet: Lake Garda in Italy is more than 100 times larger.
