Application You would like to construct a box that has a base length that is twice the width of the base. You know that the material to build the top and bottom costs $9/m2 and it costs $6/m2 for the sides. You would like the box to have a total volume of 70 m3. Determine the length, width, and height of the box (in metres) that will minimize the cost of production. What is the minimum cost?
