Geometry 10-1 Solids Face: the flat side of a figure Edge: a straight line connecting sides Vertex: a corner where edges intersect

Basic Shapes Prism: 2 polygon bases, rectangle faces Cylinder: 2 circle bases, curved face Pyramid: 1 polygon base, triangle faces connect to a vertex Cone: 1 circle base, 1 curved side connects to a vertex

Name that Shape Prisms and pyramids are named according to the shape of the base. 1 2 3 4 5 6 7 8

Example Classify the solid shape. pentagonal pyramid vertices: A, B, C, D, E, F edges: faces: 6 total (1 base)

Example Classify the solid shape. cone vertex: N M edges: cones don’t have edges faces: 2 total (1 base)

Volume and Surface Area Volume: how much can fit inside of a shape Surface area: total area of all faces Lateral Surface area: area of side faces. Does not include the base(s).

Prisms Volume: V = Bh B = area of the base shape h = distance between bases

Prisms Total Surface Area: S = Ph + 2B Lateral Surface Area: S = Ph P = perimeter of base shape
