1. 12.2 – Surface Area of Prisms And Cylinders

2. Polyhedron with two parallel, congruent bases Named after its base Prism:

3. Surface area: Sum of the area of each face of the solid

4. Surface area: Sum of the area of each face of the solid Back Left Top Bottom Front Right

5. Lateral area: Area of each lateral face

6. Right Prism: Each lateral edge is perpendicular to both bases

7. Oblique Prism: Each lateral edge is NOT perpendicular to both bases

8. Cylinder: Prism with circular bases

9. Net: Two-dimensional representation of a solid

10. Surface Area of a Right Prism: SA = 2B + PH B = area of one base P = Perimeter of one base H = Height of the prism H

11. Surface Area of a Right Cylinder: H SA = 2B + PH
