Write a program to find the Surface Area of a Triangular Prism

Before writing the program of calculating the area of a triangular prism in different programming languages, firstly we have to know about the triangular prism and its formula.

What is Triangular Prism?

Triangular Prism is a 3-D shape, which has 5 faces, 6 vertices, and 9 edges.

Area of Triangular Prism

As, the prism contains 2 triangles and 3 rectangles. So,

  Surface area of Triangular Prism = (b * h) + (L * (s1 + s2 + s3))  Where, b is the bottom edge of base triangle, L is the prism length, h is the height of base triangle, and s1, s2, and s3 are the three edges of base triangle.   

Program of calculating the area of a triangular prism in different Programming languages

Program 1: Write a Program in C language:

  // This program which uses a function to find the area of a triangular prism.  #include   float find_area_of_Triangular_prism(float L, float b, float h, float s1, float s2, float s3) // It is a function to find area   {   float area_of_Triangular_prism ;  area_of_Triangular_prism = (b * h) + (L * (s1 + s2 + s3)); // It is a formula for calculating the area of triangular prism    return (area_of_Triangular_prism );   }   float main()   {   float b = 9, h = 5, s1 = 3;   float s3 = 6, s2 = 8, L = 8;  printf(“Surface area of the triangular prism  is: %f”, find_area_of_Triangular_prism(L, b, h, s1, s2, s3));     return 0;   }  

Output of Above C program:

Surface area of the triangular prism  is: 181.000000

Program 2: Write a Program in Java language:

  // This is a Java program which finds the area of a triangular prism .  class findarea {   static float find_area_of_Triangular_prism(float L, float b, float h, float s1, float s2, float s3)   {    float area_of_Triangular_prism ;  area_of_Triangular_prism = (b * h) + (L * (s1 + s2 + s3)); // It is a formula for calculating the area of triangular prism    return(area_of_Triangular_prism);   }   // Driver method   public static void main(String[] args)   {   float b = 3, h = 4, s1 = 3, s2 = 6;   float s3 = 6, L = 8;  System.out.println(“The area of a triangular prism  is:”);  System.out.println(find_area_of_Triangular_prism(L, b, h, s1, s2, s3));   }   }  

Output of Above Java program:

The area of a triangular prism  is:  132.0

Program 3: Write a Program in PHP programming language.

  <?php   // This is a PHP program which finds the area of a triangular prism.    // Function to find area   function find_area_of_Triangular_prism($L, $b, $h, $s1, $s2, $s3)   {     $area_of_Triangular_prism  =($b * $h) + ($L * ($s1 + $s2 + $s3)); // It is an statement which uses a forumla to find the surface area and store the value in the area_of_triangular prism variable.   return ($area_of_Triangular_prism);   }   $b = 4;   $h = 4;    $s1 = 6;   $s2 = 9;   $s3 = 2;   $L = 1;  echo find_area_of_Triangular_prism($L, $b, $h, $s1, $s2, $s3);   ?>  

Output of Above PHP program:

Program 4: Write a Program in Python programming language.

  # This is a python program which finds the area of a triangular prism .   def find_area_of_Triangular_prism(L, b, h, s1, s2 ,s3):      return ( (b * h) + (L * (s1 + s2 + s3)) ) # It is a formula which finds the value of area.  # main code begins   b = 4;   h = 4;    s1 = 6;   s2 = 9;   s3 = 2;   L = 1;  print(find_area_of_Triangular_prism(L, b, h, s1, s2, s3) )  

Output of Above Python program:
