Homework Help: Open Box Optimisation

  1. Jul 29, 2017 #1
    1. The problem statement, all variables and given/known data
    A box is given with a L = 1.414w and W = w and a cut size = x. Find the general formula for the maximum volume.

    2. Relevant equations
    L = 1.414w - 2x
    W = w - 2x
    H = x

    3. The attempt at a solution
    V = x(1.414w - 2x)(w - 2x)
    V = 4x3 - 4.818x2w + 1.414w2
    Apparently this isnt the general formula for max volume, so someone please help.
