Introduction

Do we live in a regular or irregular world? Wouldn't it be nice and neat if all polygons in our world were regular with all of their sides and angles congruent? Did you know that most of our formulas for finding area and volume were written for regular polygons? In this lesson, we will look at ways to find surface area and volume of irregular shapes.

several different types of regular and irregular shapes
