Lesson 12.2: Surface Areas of Prisms and Cylinders
Key Concepts: Surface Areas of Prisms and Cylinders
Lateral Area of a Prism
L = Ph
where P is the perimeter of the base and h is the height.
Surface Area of a Prism
S = Ph + 2B
where B is the area of one base.
Lateral Area of a Cylinder
L = 2πrh
Surface Area of a Cylinder
S = 2πrh + 2πr²
