    1. The problem statement, all variables and given/known data

    A room has dimensions 2.95 m (height) × 4.68 m × 6.19 m. A fly starting at one corner flies around, ending up at the diagonally opposite corner. (a) What is the magnitude of its displacement? (b) If the fly walks rather than flies, what is the length of the shortest path it can take?

    2. Relevant topic

    3. The attempt at a solution
    SQ RT √(2.952+ (x)2); x = SQ RT of √(4.682 + 6.192)
    = 8.30

    Part B, I have problems with as I do not know which one is width/length : (

    The answer is
    SQ RT
    √((w+h)2 + (l)2)
    But because I do not know which is which I have a slight dilemma... Is there a way to tell?

    Shorter distance is width.
