OVERVIEW:

This animation introduces the importance of surface area to volume ratio in nanoconcept. As bigger cubes are build, the SA/V ratio decreases. Smaller particles have higher SA/V ratio, which is an importance property for many chemical processes.

This animation can be used in a math class (algebra or geometry) as an introduction to SA or volume and an introduction to ratios. It can be used as an activity for teaching student about surface area and volume calculations of a cube.
