Introduction
pg 450In Lessons 9.1.1 and 9.1.2, you investigated volume, surface area, and special three-dimensional solids called prisms. Today you will explore different ways to find the volume and surface area of a prism and a related solid called a cylinder.
You
will also consider what happens to the volume of a prism or cylinder if it slants to one side or if it is enlarged proportionally.Slide5
Problems 9-25
9-28Explore what will happen to volume and surface area of new types of 3-D solidsSee if you can observe a general patternSlide6
What if bases of prism are not rectangular?
What if sides are not perpendicular to bases?Slide7

Wrap-Up Questions
What connections did you make today to previous material?How are prisms and cylinders alike? Different?How are similar solids related? How does the volume of a solid change when the solid is enlarged proportionally?What are the different representations of a three-dimensional solid and how does each help you find the volume and/or surface area?Why does the volume of a prism or cylinder stay constant when it is slanted in any direction (assuming the height remains constant
)?
