2. A covered box is to be made from a rectangular sheet of cardboard measuring 5ft. by 8ft. This is done by cutting out the shaded regions of the diagram below and folding on the dotted lines. What are the dimensions x, y, and z that result in the largest volume of the box? Write an equation for the quantity to be optimized. 1. ii. Read the problem again and using the information given write two equations relating variables. Using the relationships found in part (b), reduce your equation in (a) to an 111. equation in one variable (write it in terms of x) and simplify. iv. What is the domain (range of possible values for x)? Use appropriate test to find the optimal value. V. vi. Read the problem again and report your conclusions.
