A box with a square base and open too must have a volume of 415292 cmg. We wish to find the dimensions of the box that minimize the amount of material used. First, find a formula for the surface area of the box in terms of only at, the length of one side of the square base. W: Next, find the derivative, A ' (:13). M) = S The critical value is a: = [:1 The function is until the critical value, and v after, so the critical value corresponds to a local v
