a) The box with the square base has volume of 867 in3. State surface area of box as the function of length x of side of the base. Use function to compute dimensions of box with volume 867 in3 and smallest possible surface area.
b)i) Cylindrical can has the surface area of 60 in2. State volume of can as the function of radius r.
ii) Use function in part a to compute radius and height of can with surface area 60 in2 and largest possible volume.
