Rectangular Prisms

A one stop resource

The geometry of rectangular prisms  is almost identical to that of the square prism, and is the most common of all the prisms to have questions based upon it in standardized tests.  

The rectangular prism is also known as a cuboid.  

It is also the most commonly used prism in real life used in packaging, from cereal boxes to parcel delivered by mail.  So the next time your family finishes a box of cereal, be sure to keep the box, so you can open it up and use it as a prism 3d-net for exploration purposes for your child.
