- Prism is a 3 dimensional shape with 2 congruent polygon bases and rectangular sides.
- Prism the shape of prisms base gives its name.
The base is the shape you see the least of or THE OTHER SHAPE BESIDES THE RECTANGLE
- A Prism doesn't have a apex. Pointy TOP only pyramids.
- A Prism can have triangle and or rectangle bases.
There is no such thing as a prism pyramid.

• Pyramid are solid figures with one base and all other sides are triangles that meet at one point called an apex.

• The lateral faces of a rectangular pyramid are triangles.

• Pyramid bases can be triangle or rectangle.

•  $Area\ =Bh$   $Volume=\ \frac{1}{3}Bh$
