21. Tracing around the OUTSIDE of the box, what is the shortest distance from point A to point B?
The answer key explains that its B and they give an explanation with the box opened up going. However, I am confused as to why we couldn't just do √(x^2 + y^2 +z^2). So it would be √(81+25+9) to get the distance from A to B, which would give us the answer A of √115.
