Question 1

\fThe packaging department in a company has been asked to design a rectangular box with no top and a partition down the middle as shown in the figure. Let x, y, and z be the dimensions of the box (in inches) Ignore the thickness of the material from which the box will be made. Answer parts (A) and (B) below. (A) Find the total area of material M(x,y,z) used in constructing one of these boxes M(x,y.z) = Evaluate M(11,10,5). M(11,10,5) = - > cubic inclus, inches of square inches (B) Suppose that the box will have a square base and a volume of 640 cubic inches. Use graphical approximation methods to determine the dimensions that require the least material. The dimension of one side of the base is and the dimension of the height (z) is Type integers or decimals rounded to two decimal places as needed.)
