    Surface Area of Prisms and Cylinder

    Learning Intentions:Given a review of 3D solids students will recognize their corresponding net and find their surface area of a prisms and cylinder.

    Unit 2 Module 3.2

    Success Criteria:I will be able to recognize the net of a 3D solid.

    I will be able to find the surface area of a 3D solid.

    Surface Area: the total area of all the faces and curved surfaces of a 3D figure.

    Vocabulary

    Lateral Area: the total area of the lateral faces not including the bases of a 3D figure.

  • Unit 2 mod 3.2 Surface Area Prisms & cylinders.notebook January 10, 2018

    1. In the net, what type of figure is formed by the lateral faces of the prism?

    2. Write an expression for the length of the base of the rectangle?

    3. How is the base of the rectangle related to the perimeter of the base?

    4.  The lateral area of the prism is the area of the rectangle, write a formula for the lateral area of the prism.

    5.  Write a formula for the surface area of the prism.

    1. Explain why the net of the lateral area of  any prism will always be a rectangle.

    2. Suppose a rectangle prism has length l, width w, and height h, as shown.  Explain how you can write a formula for the surface area of the prism in terms of l, w, h.
