1. Find the lateral area and the surface area of each figure.
Round to the nearest tenth, if necessary.
1. a cube with edge length 10 cm
2. a regular hexagonal prism with height 15 in. and base
edge length 8 in.
3. a right cylinder with base area 144 cm2 and a height
that is the radius
L = 400 cm2 ; S = 600 cm2
L = 720 in2; S 1052.6 in2
L 301.6 cm2; S = 1206.4 cm2

2. 4. A cube has edge length 12 cm. If the edge
length of the cube is doubled, what happens to the surface
area?
5. Find the surface area of the composite figure.
The surface area is multiplied by 4.
S = 3752 m2
3. OBJECTIVE
To define and find the
lateral area, surface
area, and volume of
a regular pyramid
and a cone
4. vocabulary
• base - polygon
• lateral faces - triangles
• vertex - point where lateral
faces meet
• altitude - segment from the
vertex perpendicular to the
plane of the base
5. vocabulary
• pyramid - a polyhedron which
consists of one base and lateral
faces which are triangles
• regular pyramid - base is a
regular polygon
6. vocabulary
• right pyramid - the altitude
intersects the base at its center
• oblique pyramid - the altitude
intersects the base at a point
other then the center
