This answer is wrong. There are 3 ways to travel to any point on the box. If I choose a point that is 1/4 to the left of B and 1/4 down from B, I get a distance squared of 8.125 for all three paths. The min of these distances is 8.125.
HOWEVER if I chose a point 0.2 units to the left of B and at the same height as B, I get a distance squared of 8.84 from two of the paths and a distance squared of 9.64 from the other path. The min of these is 8.84. Clearly 8.84>8.125.
Pic related is the 3 possible paths one can take to any point.
