1
**Volume of Prisms and Cylinders**

2
Lesson Objective Students will use the formula for the volume of a prism and cylinder to solve problems.

3
Lesson Beginning Based on the exploratory activity, tell me three things that you learned about volume of cylinders.

4
**Volume (V) is a measure of the amount of space that it occupies.**

5
Volume of Prisms Volume of a prism is the product of the area of the base and the height of the prism. V = Bh

6
Volume of Cylinder Volume of a cylinder is the product of the area of the base and the height of the cylinder. V = Bh

7
Modeling Find the volume.

8
Modeling Find the volume.

9
Practice Find the volume.

10
Practice Find the height of the cylinder. Round your answer to the nearest whole number.

11
Practice A movie theater designs two bags to hold 96 cubic inches of popcorn. (a) Find the height of each bag. (b) Which bag should the theater choose to reduce the amount of paper needed? Explain.

12
Practice How much salsa is missing from the jar?

13
Practice A cylindrical water tower has a diameter of 15 meters and a height of 5 meters. About how many gallons of water can the tower contain? (1 𝑚 3 ≈ 264 gal)

14
As time allows 25) Which has a greater effect on the volume of a cylinder: doubling the height or doubling the radius? Which has a greater effect on the volume of rectangular prism that is longer than it is wide: doubling the length or doubling the width? Explain?

15
As time allows 36) Two prisms have different surface areas. Can they have the same volume? Explain.
