Volume of Composite Figures

The video explains how volume is additive by finding the volume of a composite 3D figure made of two rectangular prisms. It demonstrates how to divide a complex figure into simpler parts, calculate the volume of each part using formulas, and then sum these volumes to find the total volume. The process involves identifying dimensions, substituting values, and performing arithmetic to reach the final answer of 24 cubic inches.

What is the formula to calculate the volume of a rectangular prism?

• 2 x (Length + Width + Height)

• Length x Width x Height
