12.2 – Surface Area of Prisms And Cylinders

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

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

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

Lateral area: Area of each lateral face

Right Prism: Each lateral edge is perpendicular to both bases

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

Cylinder: Prism with circular bases

Net: Two-dimensional representation of a solid

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

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