Lesson 3: Introduction to Volume and Cubic Units

In this Grade 5 Pengi Math lesson from Chapter 8, students learn to define volume as the amount of space inside a three-dimensional object and recognize cubic units as the standard way to measure it. The lesson also helps students distinguish volume from area and perimeter through real-world examples, building a clear understanding of when volume is the appropriate measurement to use.

Section 1

Introduction to Volume and Cubic Units

Property

Volume is a measure of how much space is inside a three-dimensional object or how much it takes to fill a container.
Volume is always measured in cubic units such as cubic inches (in3\text{in}^3), cubic feet (ft3\text{ft}^3), cubic centimeters (cm3\text{cm}^3), or cubic meters (m3\text{m}^3).
