The postal service will accept a box for shipment only if the sum of its length and girth (the distance around) does not exceed 108 inches. What dimensions will give a box with a square end the largest possible volume?

    This is a pretty straightforward problem; have you at least made some progress towards setting it up?2012-12-09

    Could you also include a picture, labelled with appropriate variables? Doing so would show that you've put at least some effort into solving the problem...2012-12-09

    I know that you're trying to maximize volume which equals L*W*H. Since it's a square you know that W and H are equal. Since Girth plus length equals 108, that means that L+2W+2H=108. You could then solve for L which would equal 108/4w, since w=h.2012-12-09

    What you say will get you well down the path to solution.2012-12-09
