In this topic, you are going to explore the surface area, lateral area, and volume of three-dimensional figures to include practical problems and composite figures. Composite figures are figures that are composed of more than one three-dimensional figure. See if you will be able to figure out if you will be finding the surface area, lateral area, and volume of practical problems.

Essential Questions

• How are the surface area, lateral area, and volume of practical problems calculated?
• How are the total surface area, lateral area, and volume of composite figures calculated?

Warm-Up

Take a moment to look around the room. You will find that three-dimensional objects are everywhere. Did you know that geometry helped create each of these figures?
