A plastic gutter is designed to catch water at the edge of a roof. Manufacturers need to minimize the amount of material used to make their product. What is the best cross-section for a gutter? Options for cross-section are: 1. Triangular Shape 2. Rectangular Shape 3. Circular Shape I need to use optimization and calculus to solve this. Any working out you can show me would be very helpful.
