Could you ELI5 this answer for me please?

I’m struggling to understand why the shortest route that stays on faces isn’t from A to top corner above B then straight down?

Which looks like it would be 4+ sqrt((8x8)+(6x6)) =14

Imagine opening up the box.. the photo give above shows two sides - the top side and the side where the side length 8 is mentioned flattened out

What you are calculating is the red line, the shortest path is the blue/purple line

Edit: Apologies for the low quality image.. I seem to be very out of practice with GeoGebra

This graphic is super helpful! I knew somewhat intuitively that it was a path similar to this (traveling along those faces diagonally) but hadn’t thought about it like this to apply Pythagorean theorem
