A room has dimensions 2.58 m (height) × 5.89 m × 6.33m. A fly starting at one corner flies around, ending up at thediagonally opposite corner. (a) What is the magnitude of its displacement? (b) If the fly walks rather than flies, what is thelength of the shortest path it can take?
(Hint: This canbe answered without calculus. The room is like a box. Unfold itswalls to flatten them into a plane.)
