Write a program to find the Volume of Octahedron

Before writing the program of calculating the volume of an octahedron in different programming languages, firstly we have to know about an octahedron and its formula.

What is Octahedron?

Octahedron is a regular polyhedron shape, which has six vertices, twelve edges, and eight faces.

Volume of Octahedron

Volume of Octahedron = ((√2) / 3) * (a * a * a)
Where, a is the side of an 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:
