UNIT OVERVIEW

This unit teaches you how to calculate the volume and surface area of three-dimensional (3D) shapes. These skills are used every day by engineers, builders, and designers.

What you will learn:

• Calculate volume and surface area of prisms and cylinders
• Understand what happens when you scale (enlarge or reduce) shapes by a factor $k$
• Work with spheres, pyramids, and cones
• Apply these skills to real-world problems

Why this matters:

• Water tanks: Knowing the volume tells you how much water a tank holds
• Construction: Surface area tells you how much material you need (and what it costs)
• Packaging: Volume tells you how much product fits inside a container
