Textbook Problem

*In Exercises 20 and 21, use Theorem 9.2.1 in which the lengths of apothem*
*, altitude*
*, and slant height*
*of a regular pyramid are related by the equation*

In a regular hexagonal pyramid whose base edges measure

To determine

**To find:**

The length of its altitude.

Explanation

**Given:**

A regular hexagonal pyramid whose base edges measure

**Properties Used:**

A pyramid is made by connecting a base to an apex. The base is flat with straight edges, no curves, hence, a polygon and all other faces are triangles.

A regular pyramid is a pyramid whose base is a regular polygon and whose lateral edges are all congruent.

In a regular pyramid with slant height

The altitude/height

The apothem

The slant height

In a regular pyramid, the lengths of the apothem

In a right-angled triangle, the hypotenuse is the longest side.

**Calculation:**

Considering a regular hexagonal pyramid with vertex

Given that base edges measure
