Understanding Volume and Unit Measurement

This video tutorial explains how to measure the volume of three-dimensional figures using unit cubes. It covers the concept of volume as the space occupied by a figure and demonstrates how to calculate volume by counting unit cubes without gaps or overlaps. The tutorial provides examples with different unit measurements, such as centimeters, inches, and feet, to illustrate how volume is labeled accordingly. By the end of the lesson, viewers will understand how to determine the volume of a 3D figure by counting unit cubes.

What is the primary purpose of using unit cubes in measuring volume?

• To calculate the surface area of a figure

• To measure the weight of an object

• To describe the space a 3D figure occupies

• To determine the color of a figure

How many unit cubes are in a figure with a volume of 8 cubic units?
