Formula MathFormula Math Of Triangular Prism Definition :

A Triangular Prism is a polyhedron made of a triangular base, a translated copy, and 3 faces joining corresponding sides.
Formula Math Of Triangular Prism :

Area of Base [ A ]        =  ½ . a . b
Perimeter of Base [ P ] =  s.1 + s.2 + s.3
Surface Area of Prism  = a.b + [s.1+ s.2 + s.3].h = a.b + P.h
Volume of Prism           =  ½ . a . b . h = A.h
Note :
        a = altitude, b = base, h = height and s1, s2, s3 are sides

Example

Question : Find the surface area and volume of a triangular prism with the given altitude 2, base 3, height 4 and the sides 1, 2, 3.

Question : Find the area of the base.
Answer :   Area of the base [ A ] = ½ . a . b = 0.5 . 2 . 3 = 3.

 Question : Find the perimeter of the base.
 Answer :  Perimeter of the base [ P ] = s.1 + s.2 + s.3 = 1 + 2 + 3 = 6.
 Question : Find the surface area of prism.
 Answer :   Surface Area of Prism = a.b + P.h = [ 2 . 3 ] + [ 6 . 4 ] = 6 + 24 = 30.

Question : Find the volume of prism.
Answer :  Volume of Prism = A.h = 3 . 4 = 12.

That is  example Formula Math Of Triangular Prism Definition will clearly illustrates how to calculate the Volume, Surface Area, Perimeter of a Triangular Prism.
