12.2 Surface Area of Prisms & Cylinders

2. SURFACE AREA OF PRISMS AND CYLINDERS
A polyhedron with two congruent faces (bases) that lie in parallel planes.
The lateral faces are parallelograms
The height is the perpendicular distance between the bases
Surface Area: the sum of the areas of its faces
Lateral Area: the sum of the areas of the lateral faces

3. Surface Area of a Right Prism
SURFACE AREA OF PRISMS AND CYLINDERS
Surface Area of a Right Prism
The surface area, S, of a right prism is:
S = 2B + Ph
B = area of one base
P = perimeter of one base
h = height of the prism
2B represents the “base area”
Ph represents the “lateral area”

4. SURFACE AREA OF PRISMS AND CYLINDERS
A solid with congruent circular bases that lie in parallel planes.
Lateral area: the area of its curved surface

5. Surface Area of a Right Cylinder
SURFACE AREA OF PRISMS AND CYLINDERS
Surface Area of a Right Cylinder
The surface area of a right cylinder is:
S = 2B + Ph which can be written as
S = 2πr2 + 2πrh OR
2πr (r+h)
