In this lesson for grades 6-12, learners explore the relationship between dimension and volume. Using colored paper, students create two rectangular prisms and two cylinders to determine which holds more popcorn. They then justify their conclusions by analyzing the formulas and identifying dimensions with the largest impact on volume. Editor's Note: This activity presents an excellent opportunity for students to gain real insight into why increasing the radius of a cylinder has more impact on volume than increased height. It will also promote understanding of why the formulas for calculating volume work. This resource includes lesson objectives, teaching tips, and student worksheets with answer keys provided. It is part of a larger collection of activities developed by the National Council of Teachers of Mathematics (NCTM).
