More Practice Problems: #18 on p.215 A piece of cardboard measures 10- by 15-in. Two equal squares are removed from the corners of a 10-in. side as shown in the figure. Two equal rectangles are removed from the other corners so that the tabs can be folded to form a rectangular box with lid. (d) Confirm this answer analytically. when at our critical point, meaning that this point corresponds to a maximum volume.
