A warehouse is installing a pulley system from the corner of the floor, X, to the opposite corner of the ceiling, Y. This will require a rope that runs directly from X to Y and directly back to X in a straight line.
The warehouse is 100m by 50m by 20m.
How much rope is needed for the pulley system?
The diagonal through the rectangular prism will be
sqrt ( 100^2 + 50^2 + 20^2) and you will need TWO times this distance = 227.16 meters
