1-6 Volume of a Prism

Volume of a Prism

Introduced in Lesson 42

Warm Up

Find the volume of this cube. How did you get it?

Notebook: Learning & Habit Objectives

Learning: I will calculate the volume of any type of prism

Habit: I will write each step of work to stay organized

Success Criteria

• I know my vocabulary

• I can identify the bases and height of a prism

• I can use the formula V = Bh to solve for volume of any type of prism

Notebook: Identifying Prisms

• A prism is a 3-dimensional figure with two bases that are polygons

• The distance between the two bases is the altitude or height

• The faces of the prism that are not bases are called lateral faces

• The volume of a prism is the amount of space that is occupied inside the shape. Volume units are to the power of 3, so cm³, in³, ft³,...

Notebook: Volume Formula

V = Bh, V is volume, B is area of one base, and h is height or altitude

Open Ended

Use V = Bh to find the volume of this triangular prism

What if the base is irregular?

No problem! Find the area of that irregular base and then multiply by the height of the prism

Open Ended

Find the volume of this prism

Exit Ticket

Find the volume of this prism using V = Bh. You will enter your work and answer on the next slide.

Open Ended

Find the volume of this prism. The key is to stay organized in finding the area of the base.
