The Volume of Prism Shapes
The volume of prism shapes - ANY PRISM is simply the area of its base multiplied by the length of the prism. That is it for EVERY and ANY prism. But
the question most curious elementary students will ask is "why?"
If this is the point your child is at, then you are in the right place to get exactly the information you need to explain it. Of course your child
should fully understand what area, surface area and volume are; and know how to calculate area of 2d shapes to get the most out of this section.
Before we start, let's be sure we fully understand what the definitions of 'volume' and 'prism' are:
Definition of Volume:
This is the amount of space contained within a three dimensional shape.
Definition of Prism:
This is a three dimensional shape, where the front and back faces are two identical polygons, and both
polygons are connected by parallel lines. These parallel lines will ensure that a a cross
section ANYWHERE on the prism will yeild the same identical polygon.
The Triangular Prism
I am going to use the triangular prism as my example to explore the origins of the volume of a prism formula.
