a woman wants to construct a box whose base length is twice the base width. The material to build the top and bottom is $ 9/m ( squared) and the material to build the sides is $6m/ ( squared). If the woman wants the box to have a volume of 70 m cubed, determine the dimensions of the box ( in meters) that will maximize the cost of production. What is the minimum cost?
