Surface Area = 6 x Length^2
Volume = length^3
8 vertices
6 faces
12 edges
Volume = length x height x width
Surface Area = (2 x length x height) + (2 x height x width) + (2 x length x width
vertices = n + 1
Faces = n + 1
edges = 2n
Surface Area = Base area x total of triangle area (pyramidal blanket area)
Volume = 1/3 x base area x height
Example : Rectangular pyramid (n=4) edges = 8
Example : triangular pyramid (n=3) vertices = 4
Example : Pentagonal pyramid (n = 5) Faces = 6
Vertices = 2n
Edges = 3n
Faces = n + 2
Volume = Base area x height
Surface Area = 2 x base area x total of the rectangle area (prism blanket area
Example : Triangular prism (n = 3) edges = 9
Example : Hexagonal prism (n = 6) vertices = 12
Example : Octagonal Prism (n = 8) Faces = 10
