SURFACE AREA OF PRISMS AND CYLINDERS GUIDED PRACTICE SURFACE AREA OF PRISMS AND CYLINDERS Section 12.2

GUIDED PRACTICE Prism: a polyhedron with 2 congruent, parallel bases. The surface area is the area of all the sides and bases. The lateral surface area is the area of all the bases. Lateral Surface Area: S = Ph, where P=perimeter of the base and h= height Total Surface Area: S = Ph + 2B, where B=area of base

GUIDED PRACTICE Cylinder: solid with congruent, parallel bases. The lateral surface area is the area of the curved surface. The surface area is the lateral surface area and the bases. Lateral Surface Area:, Total Surface Area:

EXAMPLE 1 Find the surface area of a rectangular prism with height 2 centimeters, length 5 centimeters, and width 6 centimeters.

GUIDED PRACTICE Find the surface area of a right rectangular prism with height 7 inches, length 3 inches, and width 4 inches.

GUIDED PRACTICE Find the surface area of a right cylinder with height 18 centimeters and radius 10 centimeters. Round your answer to two decimal places.
