You must show all Calculus steps by hand to get credit. AND, you mustjustify you have indeed found dimensions which maximize the area of the rectangle [as opposed to minimize} by using one of the following methods: the fist derivative test. or the 2nd derivative test. or a calculator generated graph which you copy to your paper. A] A closed box of volume 20 cm3 with a square base is to be constructed. Using derivatives, nd the dimensions of the box that minimize the amount of material used in its construction. Exact value answers only write in radical form. B] The graph of y e i" is shown below. Find the dimensions of the rectangle of maximum area that can be inscribed. as shown. in the rst quadrant with one corner on the graph of flat}
