Volume of Prisms and Pyramids
Name_______________________________________________
Pyramid: has one base, that’s a polygon.
The faces are triangles that all meet at a vertex.
Big Idea: If a pyramid and a prism have the same height and same base,
then it will take three pyramids to fill the prism.
Draw a picture of the above idea:
Therefore, what must the volume formula for a pyramid be:
Volume of a Pyramid:
V=
