How Can We Fit the Global Population into One Building?
Not that we foresee an instance of needing to put all 7.3 billion humans in one place, but what would it look like to put every single person in the same building? The team at Real Life Lore developed this follow-up question after their video for "What If Everybody Lived in Just One City?" Strangely enough, the building wouldn't take up nearly as much space as you'd think. The cube would measure love .8 miles (1.3 km) on each side. Granted, this cube certainly doesn't accommodate for comfort. Everyone gets a coffin-sized space in this hypothetical discussion. Apologies in advance to anyone who is claustrophobic.
