Consider the problem of cutting corners out of a rectangle and folding up the sides to make a box. Specific examples of this problem are discussed in Example 3 and Exercise 21. (a) In the solution to Example 3, compare the area of the base of the box with the area of the walls. (b) Repeat part (a) for the solution to Exercise 21. (c) Make a conjecture about the area of the base compared with the area of the walls for the box with the maximum volume. g
