A project-based lesson where students redesign the soda can. After reviewing volume of rectangular prisms, students determine the volume of a can of soda in cubic inches. They use this volume to re-design the soda can so that their can has the same volume.
Students will need to use the area of polygons such as rectangles, triangles, parallelograms, and trapezoids in the design of their new can. They begin by creating a net being careful to keep the volume the same as the cylindrical can.
As an additional "lesson", students make predictions about whether the volume of a rectangular prism changes as that prism takes on the shape of a cylindar.
