12.2 Surface Area of Prisms and Cylinders

• Lateral face
• Oblique

2
Definition of a Prism

• A Prism is a solid having bases or ends that are
  parallel, congruent polygons and sides that are
  parallelograms.

3
Parts of a Right Prism

• Height is the distance between the bases

4
Different Right Prisms

• All Prisms with a Right angle

5
Definition of an Oblique Prism

• A prism with angles that are not right angles.

6
A way to show the surface of a Prism

• A two Dimensional representation of a prism is
  called a net

7
Right Prism Theorem

• The Surface Area of a Prism is two bases plus the
  lateral faces.
• Lateral faces Height times Perimeter
• B is Base
• P is Perimeter
• H is Height

8
Right Prism Theorem

• The Base is 4(7) 28
• Perimeter is 2(4)2(7) 22
• Height is 5
• S.A. 2(28) 22(5)
• S.A. 166

9
Another way is adding all the faces and bases

• The equation
• S.A. 2(WH WL HL)
• W 4 L 7 H 5

10
Define of a Cylinder

• A Prism with a circular base

11
The net of a Cylinder

• Two circles and a Rectangle

12
The Surface Area of a Cylinder

• 2 Bases Circumference times height

13
The Surface Area of a Cylinder

• 2 Bases Circumference times height

14
The Surface Area of a Cylinder

• 2 Bases Circumference times height
