If you made a book that included everyone’s face in the entire world, how much would it weigh?
World’s current population: 6,967,598,508
For experiment’s sake, use thumbnail photos of everyone’s faces—6 faces to a page, 12 to a sheet (double-sided, we care about the environment, duh!).
Sheets of paper required: 580,633,209
There are 500 sheets of paper in a ream, so 1,161,266.42 sheets (let’s just round down, shall we?).
Apparently, a standard ream of paper weighs 5 pounds. So, that’s 5,806,330 pounds of paper.
Based on some averages of adult elephant weight (let’s just say 10,000 pounds, why don’t we?), the book would weigh as much as 580.633 elephants.
