| Video Discription | What's the average area of a cube's shadow? Numberphile video on Bertrand's paradox: https://youtu.be/mZBwsm6B280 Help fund future projects: https://www.patreon.com/3blue1brown An equally valuable form of support is to simply share the videos. There's a small error at 19:30, I say "Divide the total by 1/2", but of course meant to say "Multiply..." Curious why a sphere's surface area is exactly four times its shadow? https://youtu.be/GNcFjFmqEc8 If you liked this topic you'll also enjoy Mathologer's videos on very interesting cube shadow facts: Part 1: https://youtu.be/rAHcZGjKVvg Part 2: https://youtu.be/cEhLNS5AHss I first heard this puzzle in a problem-solving seminar at Stanford, but the general result about all convex solids was originally proved by Cauchy.
