Problem 1: An open box (i.e. no top) is to be made from a square piece of material, 24 inches on a side, by cutting equal squares from the corners and turning up the sides (see figure). Find the maximum volume of the box. Problem 2: A Norman window is pictured below. This type of window has the shape of a rectangle surmounted by a semicircle. If the perimeter of the window is 30 ft, find the dimensions of the window so that the greatest possible amount of light is admitted.
