10.1 Surface Areas of Prisms and Cylinders
1. The amount of material used to cover a
container is described by the SURFACE AREA (SA).
2. The amount of fluid that a container will
hold is described by its VOLUME.
The total area of the lateral faces of a prism
or cylinder is described by its LATERAL AREA (LA).
This is calculated by finding the SUM of the
AREA of the NUMBER of LATERAL faces.
LA = PERIMETER x HEIGHT
Perimeter (circumference)
of the base
Height between 2
bases
5. The surface area of a figure is
calculated by adding the LATERAL AREA
and twice the area of a BASE.
SA = L.A. + 2B
Lateral Area
of the prism
or Cylinder
2 x Base area
(Since there's
2 bases)

12. A right hexagonal prism has a base area
of 84mm2, a base perimeter of 36mm, and a
height of 32mm.
