Finding the Volume of an Irregular 3D Solid: Additive Property of Volume

This lesson explains that volume is additive by demonstrating how to find the volume of a 3D figure composed of two rectangular prisms. It covers the basic formula for calculating the volume of a rectangular prism and applies it to a complex shape by dividing it into simpler parts. The lesson also includes determining missing edge lengths and calculating the composite volume of the shape.

What is the volume of the blue rectangular prism?

Summarize the conclusion about the composite 3D solid's volume.
