Minimizing Surface Area of a Cylinder Given a Fixed Volume

Activity Overview

Students will discover the relationship between radius and height of a cylinder so that surface area of a cylinder can be minimized while maintaining a fixed volume. This is just an introduction to a project that they will begin after this investigation. Once this is completed, they will redesign the packaging of a cylindrical can so that the least amount of material is used to hold the specified volume. Notes regarding the project are not included.
