 * Surface Area and Volume of Prisms

Altitude of a prism:** How tall one segment is that is perpendicular to two planes. [|Altitude of a prism]


 * Height of a prism;** The length of the alitude.

The area of a prism may be broken down into two parts: the area of the bases, and the area of the lateral faces. The surface area is S=L + 2B or S=hp + 2B
 * Finding the surface area of a right prism:**

Volume of a prism: V = Bh
 * Formula for finding the volume of a right prism:**

If 2 solids have equal heights and the cross sections formed by ever plane parallel to the bases of both solids have the same areas, then the 2 solds have the same volume.
 * Cavalieri's principle:**

These stacks of coins have the same voume according to Cavalieri's principle.
