1. 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(W·H + W·L + H·L)
W = 4; L = 7; H = 5

10. Definition 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
