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 cm2. a regular hexagonal prism with height 15 in. and baseedge length 8 in.3. a right cylinder with base area 144 cm2 and a heightthat is the radiusL = 400 cm2 ; S = 600 cm2L = 720 in2; S 1052.6 in2L 301.6 cm2; S = 1206.4 cm2GT Geometry 5/1/13 Drill 4.10• Put hw and a pen on the corner of your desk.
4. A cube has edge length 12 cm. If the edgelength of the cube is doubled, what happens to the surfacearea?5. Find the surface area of the composite figure.The surface area is multiplied by 4.S = 3752 m2
OBJECTIVETo define and find thelateral area, surfacearea, and volume ofa regular pyramidand a cone
vocabulary• base - polygon• lateral faces - triangles• vertex - point where lateralfaces meet• altitude - segment from thevertex perpendicular to theplane of the base
vocabulary• pyramid - a polyhedron whichconsists of one base and lateralfaces which are triangles• regular pyramid - base is aregular polygon
vocabulary• right pyramid - the altitudeintersects the base at its center• oblique pyramid - the altitudeintersects the base at a pointother then the center
vocabulary• slant height of a pyramid - thelength of an altitude of a lateralface.
Naming a Pyramid•Pyramids are namedaccording to the shape oftheir bases
