Lesson Plan

Boxed In and Wrapped Up

Curated and Reviewed by Lesson Planet

If cubes have the smallest surface area, why aren't there more cube-shaped packages? Scholars take a box in the shape of a rectangular prism, cut it up, and make new boxes in the shape of cubes with the same volume. They then brainstorm why most packages aren't in the shape of cubes even though they use less material.
