# Lesson Plan: Volumes of Pyramids Mathematics

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to find the volume of a pyramid and solve problems including real-life situations.

#### Objectives

Students will be able to

• recall the formula for the volume of a pyramid,
• find the volume of a pyramid with known side lengths (where the height of the pyramid can be calculated) when the pyramid base is one of the following:
• a triangle,
• a regular polygon with more than 4 sides (pentagon, hexagon, etc.),
• an arbitrary polygon with a given area,
• calculate a missing length of a pyramid when given its volume,
• use knowledge of the volume of a pyramid to solve problems presented as real-life systems.

#### Prerequisites

Students should already be familiar with

• the slant height and the perpendicular height of a pyramid,
• right pyramids,
• the Pythagorean theorem,
• trigonometry,
• finding the area of an n-sided regular polygon.

#### Exclusions

Students will not cover

• cones,
• the surface area of a pyramid.
