Finding the Volume of a Rectangular Prism

This lesson teaches how to find the volume of a rectangular prism by developing a formula. It reviews the concepts of perimeter, area, and volume, emphasizing the use of unit cubes to calculate volume. The lesson uses a practical example of a moving truck to demonstrate how to fill a rectangular prism with unit cubes and calculate its volume. It concludes by verifying the calculation using the volume formula.

What does the perimeter of a shape measure?

• The space inside a three-dimensional shape
