I get this when I type in your answer, which thank you by the way. "Sorry that's not correct. To simplify the problem, imagine that the wrapped post is cut lengthwise. When the post is pressed flat, the ribbon lies in straight segments, each of which is the hypotenuse of a right triangle." Also forgot to include the fact that the columns are cylindrical, if that matters or helps.

The stereo is located at the opposite corner from where the wire would begin to be ran. So if each corner were marked with a letter, ABCD, then let's say the stereo is in Corner A and the speaker is located in Corner C, on the ceiling. Does that help?

Unfortunately I don't recall that being in the original question. I would guess just normal size.
