Mathematics 1560 Assignment 9 Due Date: November 26, 2010 1. A rectangular container with open top is to have a capacity of 100 m 3 . The length of the base has to be 4 times of the width. The cost for the bottom of the container is \$20 per m 2 . Material for the sides cost \$16 per m 2 . Find the cost of the cheapest container to be built. 2. A piece of wire 10 meter long is cut into two pieces. One piece is bent into a square and the other is bent into a square. How should the wire be cut so that the total area enclosed is (a) largest, (b) smallest. Please note that a zero cut is permitted. 3. A closed cylindrical can is made to contain 100
