A rectangular container is open at the top and must have a volume of 10 cubic yard (see figure below). The side material cost C dollars per square yard, while material for the bottom costs 2C dollars per square yard. a) Solve for the optimal dimension using Lagrange multipliers. b) if it were desired to have the container hold 13 cubic yard instead of 10, by how much would cost be expected to increase? Use the value of $\lambda_1$ to estimate the change in cost- do not resolve the problem. (Problem 13.20 from Revelle et al.)
