Write a program to find the Volume of Octahedron

Program of calculating the volume of an octahedron in different Programming languages

Program 1: Write a Program in C language:

// This C program which uses a function to find the volume of a octahedron.  
#include <stdio.h>  
float find_volume_of_octahedron(float a) // It is a function to find volume   
{   
float volume_of_octahedron;  
volume_of_octahedron= (sqrt(2) / 3) * (a * a * a) ; // It is a formula for calculating thevolume of octahedron   
return (volume_of_octahedron);   
}   
float main()   
{   
float side;  
printf("Enter the side of the octahedron:");   
scanf("%f",&side);  
printf("Surface area of the octahedron is: %f", find_volume_of_octahedron(side));     
return 0;   
}   

Output of Above C program:

Enter the side of the octahedron:5
Surface area of the octahedron is: 58.925564

Program 2: Write a Program in Java language:

// This a  Java program which finds the volume of a octahedron.  
class findvolume {   
static double find_volume_of_octahedron(float a)   
{    
double volume_of_octahedron;  
volume_of_octahedron= (Math.sqrt(2) / 3) * (a * a * a) ; // It is a formula for calculating the volume of octahedron   
return(volume_of_octahedron);   
}   
// Driver method   
public static void main(String[] args)   
{   
float side = 120;   
System.out.println("The volume of a octahedron is:");  
System.out.println(find_volume_of_octahedron(side));   
}   
}  

Output of Above Java program:

The volume of a octahedron is:
814587.0119269028

Program 3: Write a Program in PHP programming language.

<?php   
// This a  PHP program which finds the volume of a octahedron.    
// Function to find volume   
function find_volume_of_octahedron($a)   
{     
$volume_of_octahedron = (sqrt(2) / 3) * ($a * $a * $a) ; // It is a formula which finds the volume and store the value in the volume_of_octahedron variable.   
return ($volume_of_octahedron);   
}   
$side = 10;  
echo find_volume_of_octahedron($side);   
?>  

Output of Above PHP program:

471.40452079103

Program 4: Write a Program in Python programming language.

# This is a python program which finds the volume of a octahedron.  
from math import sqrt  
def find_volume_of_octahedron(a):  
    return ( (sqrt(2) / 3) * (a * a * a)) # It is a formula which finds the value of volume.  
# main code begins   
side=100  
print(find_volume_of_octahedron(side))  

Output of Above Python program:

471404.5207910317
