Ve have a rectangular sheet of tinfoil whose dimensions are 32cm by 20cm. Equal squares are cut out at each of the corners. Can you find the maximum volume of a wooden box which can be lined by uitably bending the tinfoil to cover the base and the sides of the box? This problem can be solved using pencil \& paper basic calculus. But here, you are expected to treat it as an "Optimization with onstraints" problem, and solve it using the "Method of Lagrange Multipliers" and Matlab Symbolics. Never heard of the method? Never too late to learn! Start with a Google Search
