Surface Area & Volume Flashcards
Polyhedron
3 dimensional figures. Length, Width, & depth/height
Polygon
2 dimensional figure length and width
Volume
The capacity of a polyhedron
Surface Area
The area of all the faces of a polyhedron
Edge
The intersection of 2 face
Vertex
Where 3 edges intersect
Euler’s Formula
F + V = E + 2
Prism
A polyhedron with exactly 2 congruent, parallel faces called bases
Lateral Faces
Faces that are not parallel
Cylinder
A polyhedron with 2 congruent, parallel circular bases and one rectangular face.
Pyramid
A polyhedron with one polygon base and triangular lateral faces
Apex
The point at which face meet
Cone
A polyhedron with one circular base and an apex opposite the base
Sphere
The set of all points equidistant from a given point in space…that given point is the center
Lateral area of a Prism=
Perimeter • height
Surface Area of a Prism =
Lateral Area + 2 • Area of Base
Height of a Pyramid
The altitude of a pyramid .. The perpendicular segment from vertex to the base
L.A. of a Cylinder
2pi • r • h
S.A. of a Cylinder
L.A. + 2 • b
Slant Height
The length of the altitude of a lateral face of a pyramid
Face
