What’s The Smallest Country Where The Entire World’s Population Could Stand 6 Feet Apart?

Shrey Banga asks that question and concludes the answer is likely Portugal.

Crunching the numbers

Plugging in the current world population² and the recommended distance of 6 feet³:

n=7,773,861,168

r=6ft

we get

A_n=9.695×10¹¹ft²
=34,775mi²
