    Use the same procedure explained in previous problems of this type, and show your work.

    You have two variables, box base length a and height h. I will assume cutout corner square pieces are not used; other wiseyou will need a lot of tape to make sides from cut corners.
    (a + 2h)^2 = 6075
    The box will be made by folding up the four protruding ends of a fat looking cross, made by cutting square corners off a square that has side length a + 2h.

    Volume = a^2*h

    Express volume V in terms of a or h only and set the derivative with respect to the remaining variable equal to zero.

    Compute the two variables and the volume
