Calculating Volume of Rectangular Prisms

The video tutorial explains the concept of volume, defined as the space a solid occupies, measured in cubic units. It provides real-life examples, such as refrigerators, to illustrate the importance of understanding volume. The tutorial demonstrates how to calculate volume using base 10 blocks and introduces the formula for finding the volume of rectangular prisms. The formula involves multiplying the length, width, and height of the prism. The video also covers examples to reinforce the understanding of these concepts.
