 * 1) prism-a solid having bases or ends that are parallel, congruent polygons and sides that are parallelograms.
 * 2) base- the line or surface forming the part of a figure that is most nearly horizontal or on which it is supposed to stand.
 * 3) face- any of the bounding surfaces of a solid figure: a cube has six faces.
 * 4) Prism- a solid having bases or ends that are parallel, congruent polygons and sides that are parallelograms.
 * 5) Base- the line or surface forming the part of a figure that is most nearly horizontal or on which it is supposed to stand/ the bottom of a figure
 * 6) Face- any of the bounding surfaces of a solid figure: // a cube has six// // faces. //
 * 7) Lateral Face- The face or surface of a solid on its sides. That is, any face or surface that is not a base.
 * 1) Edge- A line where two faces meet
 * 2)  Surface Area- The total area of the exterior surface of a solid
 * 3) Right Prism- A right prism with bases that are regular polygons.
 * 4) oblique prism-A prism with bases that are not aligned one directly above the other.
 * 5) lateral area-The surface area of the lateral surfaces of a solid. Lateral surface area does not include the area of the base(s).
 * 6) pyramid-A polyhedron with a polygonal base and lateral faces that taper to an apex. A pyramid with a triangular base is called a tetrahedron.
 * 7) regular pyramid-A pyramid with a base that is a regular polygon. The apex is not necessarily directly above the center of the base.
 * 8) vertex of a pyramid-the point where the faces meet
 * 9) altitude of a pyramid- The distance from the apex to the base of a pyramid. Formally, the shortest line segment between the apex of a pyramid and the (possibly extended) base. Altitude also refers to the length of this segment.
 * 10) net-a 3-d figure drawn into a 2-d net
 * 1) formula of a pyramid = 1/3 b*h
 * 2) Cylinder: pi times r squared times height
 * 3) Cone: 1/3 pi times r squared times height
 * 4) Sphere: 4/3 pi times the radius cubed
 * 5) Surface Area of a Pyramid: Base + 2bh
 * 6) Surface Area of a Cylinder: 2 pi times radius squared plus 2 pi r times height
 * 7) Surface area of a cone: pi times radius times side height plus pi times radius squared
 * 8) Surface area of a sphere: 4 pi times the radius square

Shapes:
 * 1) Tetrahedron: 4 edges, 6 vertices, 4 faces
 * 2) Cube: 6 faces, 8 vertices, 12 edges Octahedron: 8 faces, 12 edges, 6 vertices
 * 3) Icosahedron: 20 faces, 30 edges, 12 vertices
 * 4) Dodecahedron: 12 faces, 30 edges, 20 vertices
