Introduction to Composite 3D Shapes

Composite 3D shapes are three-dimensional objects made by combining or subtracting basic solids. Many real-world objects are composite shapes, from buildings to furniture.

To find the volume or surface area of composite solids, break them into simpler parts, calculate each separately, then add or subtract as needed.

In this lesson, you'll learn to find volumes and surface areas of composite 3D shapes using addition and subtraction strategies.
