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

What is Icosahedron?

Icosahedron is a regular convex polyhedron shape. This shape contains 30 sides, 12 vertices, and 20 identical equilateral triangles.

Area of Icosahedron

Area of Icosahedron = 5 * √3 * a * a

Where, a is the side of an icosahedron.

Program of calculating the area of an icosahedron in different Programming languages

Program 1: Write a Program in C language:

// This C program which uses a function to find the area of a icosahedron.  
#include <stdio.h>  
float find_Area_of_icosahedron(float a) // It is a function to find area   
{   
float Area_of_icosahedron;  
Area_of_icosahedron= 5 * sqrt(3) * a * a ; // It is a formula for calculating a area of icosahedron   
return (Area_of_icosahedron);   
}   
float main()   
{   
float side;  
printf("Enter the side of the icosahedron:");   
scanf("%f",&side);  
printf("Area of the icosahedron is: %f", find_Area_of_icosahedron(side));     
return 0;   
}

Output of Above C program:

Enter the side of the icosahedron:5
Area of the icosahedron is: 216.506348

Program 2: Write a Program in Java language:

// This a  Java program which finds the area of a icosahedron.  
class findarea {   
static float find_Area_of_icosahedron(float a)   
{    
float Area_of_icosahedron;  
Area_of_icosahedron= (float) (5 * Math.sqrt(3) * a * a) ; // It is a formula for calculating the area of icosahedron   
return(Area_of_icosahedron);   
}   
// Driver method   
public static void main(String[] args)   
{   
float side = 3;   
System.out.println("The Area of a icosahedron is:");  
System.out.println(find_Area_of_icosahedron(side));   
}   
}

Output of Above Java program:

The Area of a icosahedron is:
77.94228

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which finds the area of a icosahedron.    
// Function to find area   
function find_Area_of_icosahedron($a)   
{     
$Area_of_icosahedron = 5 * sqrt(3) * $a * $a; // It is a formula which finds the area  and store the value in the area_of_icosahedron variable.   
return ($Area_of_icosahedron);   
}   
$side = 2.5;  
echo find_Area_of_icosahedron($side);   
?>

Output of Above PHP program:

54.13

Program 4: Write a Program in Python programming language.

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

Output of Above Python program:
