Solid Geometry Test Topics

The questions in the Solid Geometry Diagnostic Test are typical of those on the Math 2 test. In this
chapter, we’ll use these questions to review the solid geometry you’re expected to know. We will
also use these questions to demonstrate some effective problem-solving techniques, alternative
methods, and test-taking strategies that apply to solid geometry questions.

FIVE FORMULAS YOU DON’T NEED TO MEMORIZE

Some people find solid geometry intimidating because of all those formulas. On Math 2, however,
some of the scariest formulas are given to you in the directions. It’s good to know what formulas are
included in the directions so you don’t waste time memorizing them—and so that you won’t forget
to memorize all the relevant formulas that are not included in the directions. These are the
formulas that are printed in the directions.

Lateral area of a cone: Given base circumference c and slant height ℓ,

The lateral area of a cone is the area of the part that extends from the vertex to the circular base. It
does not include the circular base.
