# 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 quadrilateral,
- 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.
