Measuring Volume with Unit Cubes

The video tutorial introduces the concept of volume using a puzzle cube. It explains how smaller unit cubes are used to measure the volume of larger prisms. The tutorial demonstrates how to calculate volume by stacking layers of unit cubes and writing mathematical equations. It also covers the application of these concepts in solving word problems, emphasizing the importance of expressing volume in cubic units.
