Once decorated, it would use approximately square feet of lights.
Radius = 8ft
Height = 18ft

4. Other things we can use lateral surface area for in real life

5. What is a composite solid?
A composite solid is a 3D object formed by 2 or more other 3D objects.
Can you think of some real world composite solids?

8. Surface Area & Volume of Composite Solids
Identify each 3D figure in the object
Find the surface area of each 3D figure
Add the surface areas of each figure, but do not include the surface area where the figures meet
Volume
Identify each 3D figure in the object
Find the volume of each 3D figure
Add the volumes all together
