Hi Margie,

I donít know which edition of the book you are using.  I looked in the third
edition of Saxon Algebra 1 and couldnít find the discrepancy that you are
referring to. This is how they have defined the terms you are mentioning in
your question:

Altitude of a Prism is:  A perpendicular segments joining the planes of the
bases.

Height of the Prism: The length of the altitude is the height of the prism.

Lateral Surface Area (the area of all external surfaces except the bases) of
a Prism is calculated:  Perimeter of the base times the height of the prism.

Total Surface Area (total area of all exposed surfaces of the geometric
solid):  Lateral surface area plus the area of the two bases.

Volume (number of cubic units contained in it) of a Prism:  Area of the base
times the height of the prism.

Right Prism is defined as a prism whose lateral edges are at right angles to
the bases.  They also mention that the lateral edges in a right prism are
also altitudes.

Lots of big words used for simple ideas.  Make sure you understand the
difference between "Lateral Surface Area", "Total Surface Area"
and "Volume".  Please write back if I didnít answer your question.
