1. 12-2 Surface Area of Prisms and Cylinders
Vocab:
Lateral Faces: The solid sides of a 3-d figure
Lateral Area: The sum of the areas of the lateral faces
Surface Area: The sum of the lateral area and the area of the bases
Formulas:
Lateral Area of a Prism: Perimeter of base x height (Ph)
Surface Area of a Prism: Lateral Area + 2x the area of the base (L + 2B)
Lateral Area of a Cylinder: 2 x π x radius x height (2πrh)
Surface Area of a Cylinder: 2 π r h + 2 π r²

2. Prisms Ex 1: Find the lateral and surface area of the prism

3. Cylinders Ex 3: Find the lateral and surface area of the cylinder
