12.2-12.3: Surface Area
Name: _______________________
Lateral Area & Surface Area of Prisms
Lateral Area & Surface Area Cylinders
The lateral area of a right prism is the product of
the perimeter of the base and the height.
The lateral area of a right cylinder is the product
of the circumference of the base and the height
of the cylinder.
L.A. = Ph
The surface area of a right prism is
the sum of the lateral area and the
areas of the two bases.
LA = 2rh
The surface area of a right cylinder
is the sum of the lateral area and the
areas of the two bases
SA = 2r2 + 2rh
S.A. = 2B + Ph
