Write a program to find the Area of Tetrahedron

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

What is Tetrahedron?

Tetrahedron is simply a polyhedron shape, which has 4 triangular faces, four vertices, and six edges. If the faces are all congruent equilateral triangles, then the tetrahedron is called regular.

Area of Tetrahedron

Area of Tetrahedron = (√3 * ( a * a ))
where, a is the side of an tetrahedron.

Program of calculating the area of a tetrahedron in different Programming languages

Program 1: Write a Program in C language:

// This program which uses a function to find the area of a tetrahedron.
#include <stdio.h>
float find_area_of_tetrahedron(float a) // It is a function to find area 
{ 
float area_of_tetrahedron;
area_of_tetrahedron= ( sqrt(3) * ( a * a )); // It is a formula for calculating the area of tetrahedron 
return (area_of_tetrahedron); 
} 
float main() 
{ 
float side;
printf("Enter the side of the tetrahedron:"); 
scanf("%f",&side);
printf("Surface area of the tetrahedron is: %f", find_area_of_tetrahedron(side));   
return 0; 
} 

Output of Above C program:

Enter the side of the tetrahedron:5
Surface area of the tetrahedron is: 43.301270

Program 2: Write a Program in Java language:

// This a  Java program which finds the area of a tetrahedron.
class findarea { 
static double find_area_of_tetrahedron(float a) 
{  
double area_of_tetrahedron;
area_of_tetrahedron= ( Math.sqrt(3) * ( a * a )); // It is a formula for calculating the area of tetrahedron 
return(area_of_tetrahedron); 
} 

// Driver method 
public static void main(String[] args) 
{ 
float side = 3.9; 
System.out.println("The area of a tetrahedron is:");
System.out.println(find_area_of_tetrahedron(side)); 
} 
}

Output of Above Java program:

The area of a tetrahedron is:
43.30127018922193

Program 3: Write a Program in PHP programming language.

<?php 
// This a  PHP program which finds the area of a tetrahedron.  
// Function to find area 
function find_area_of_tetrahedron($a) 
{   
$area_of_tetrahedron = ( sqrt(3) * ( $a * $a )); // It is a formula which finds the area and store the value in the area_of_tetrahedron variable. 
return ($area_of_tetrahedron); 
} 
$side = 105;
echo find_area_of_tetrahedron($side);

Output of Above PHP program:

19095.860153447

Program 4: Write a Program in Python programming language.

# This is a python program which finds the area of a tetrahedron. 
from math import sqrt
def find_area_of_tetrahedron(a):
    return ( ( sqrt(3) * ( a * a ))) # It is a formula which finds the value of area.
# main code begins 
side = 5
print(find_area_of_tetrahedron(side) )

Output of Above Python program:
