    It's that time of the year for H.S. students to take the SAT

    A recent question that often appears in various similar forms:

    The length, width and height of a rectangular solid are 8, 4 and 1, respectively.
    What is the length of the longest line segment whose end points are two vertices of this solid?

    [PS: there's a long way and a short way to solve this problem]

    KW,

    Is this the long way or short way?

    You have the correct answer (as usual) but while this is the LONG way, it serves as the proof of the short way.
