• Question: if you got every single person in the world and tied them together how many times could it circle the world or would it even circle the world once?

      Let’s try to form the biggest conga line ever. Everyone extends their hands and puts them on the shoulder of the person in front of them. A person takes up about 50cm . There are 7.1 billion people in the world. So we multiply 50cm by 7.1 billion, we get 355,000,000,000cm. That’s 3,550,000km, or 2,205,867 miles.

      The Earth’s circumference is 40,075km (just short of 25,000 miles), so we take our really long conga line and divide it by this number. The result is that this conga line would go around the Earth a whopping 88.58 times!
