Question: a. Classical problem Find the radius and height of a cylindrical soda can with a volume of 354 cm 3 that minimize the surface area.

a. Classical problem Find the radius and height of a cylindrical soda can with a volume of 354 cm³ that minimize the surface area.

b. Real problem Compare your answer in part (a) to a real soda can, which has a volume of 354 cm³, a radius of 3.1 cm, and a height of 12.0 cm, to conclude that real soda cans do not seem to have an optimal design. Then use the fact that real soda cans have a double thickness in their top and bottom surfaces to find the radius and height that minimizes the surface area of a real can (the surface areas of the top and bottom are now twice their values in part (a)). Are these dimensions closer to the dimensions of a real soda can?
