Flat Surface Three-Dimensional Figure
PRISM
Elements
Vertices : 2n
Edges : 3n
Faces : n + 2
n = base edge
Lateral faces : n
Formula
Volume = base area x h
Surface Area = (2 x base area) + (h x perimeter of base)
Types of Prism
Triangular prism
Vertices : 6
Edges : 9
Lateral faces : 3
Faces : 5
Heptagonal prism
Faces : 9
Edges : 21
Lateral faces : 7
Vertices : 14
PYRAMID
Elements
Vertices : n + 1
Edges : 2n
Faces : n + 1
n = base edge
Lateral faces : n
Formula
Volume = 1/3 x (base area) x h
Surface Area = (base area) + (lateral area)
Types of pyramid
Square pyramid
Lateral faces : 4
Faces : 5
Vertices : 5
Edges : 8
Octagonal pyramid
Vertices : 9
Edges : 18
Lateral faces : 8
Faces : 9
CUBE
Formula
Volume = S x S x S
Surface Area = 6 x area of square
(area of square = S x S)
Elements
Edges : 12
Faces : 6
Face diagonal : 6
Lateral faces : 4
Vertices : 8
CUBOID
Elements
Vertices : 8
Edges : 12
Faces : 6
Face diagonal : 6
Lateral faces : 4
Formula
Volume = L x W x H
Surface Area = 2 (Lw +Lh + Wh)
