How to calculate if a box will fit through a hallway with a 90 degree turn
noonespecial: You can find out with a piece of string. Make the string as long as the mid-point of the box on one edge to one of its corners on the other side. Hold the string at the inside corner of the hall. If you can sweep the arc without touching any walls it will fit.If you don't know the size of the box in advance, hold the string at the corner and make the string the longest possible length that can sweep this arc. Take the sting with you to the box.What you are really doing is measuring the distance to the corner from the closest wall and then making sure the line from the box's midpoint to one of its corners is not longer. There are edge cases (ha!), but this generally works.
