At 6m 40s, the pink line is rotated to represent the height of the box. I am not quite clear about this. I would have liked a few more details. Does it always have to be positioned on the left most dot? If so why? What is the right most dot for?
I just got hung up on this exact same thing. I was able to finally get that he was talking about making a CUBED box in that instance. The height width and depth are all equal with that demonstration.
