This applet-based resource was developed by the National Council of Teachers of Mathematics as an example of how to teach about volume and surface area in the middle grades. Students manipulate the side length and scale factor of one of two rectangles. The applet provides values for volume and surface area of each rectangle, allowing students to quickly see the impact on volume of even a small change. Graphs may also be viewed, showing the cubic nature of volume and the quadratic nature of surface area.

See Related Items for another editor-recommended simulation that explores volume in both rectangular prisms and triangular prisms.

This resource is part of a larger collection of lessons, labs, and activities developed by the National Council of Teachers of Mathematics (NCTM).

Please note that this resource requires
Java Applet Plug-in.
