When it comes to helping your kids understand and apply the concepts of volume and surface area, real-world applications are key.

And there may be no better real-world connection than the familiar rectangular chocolate bar. 

The following activity gives kids an opportunity to apply their understanding of volume and surface area, including formulas, in a chocolatey context.

The activity focuses on higher-level thinking applications and requires that students be familiar with finding the area, volume, perimeter, and surface area of rectangular prisms.
