How to calculate if a box will fit through a hallway with a 90 degree turn
tocomment: Thanks for all the answers.  It's starting to make sense.  I'm relieved to see it's not an easy problem.If it helps, it's an elliptical machine I was thinking of buying (I was using a rectangular box shape as an abstraction.)I'm not sure how easily it can be disassembled.The dimensions are 22" x 57" x 66" and the hallway is 31" in the first corridor and 32" in the next, with a height of 82".
