C Program: Volume of a Cube

Introduction

A cube is a three-dimensional solid object bounded by six equal square faces.
In geometry and real life, cubes appear in dice, ice cubes, and packaging boxes.

The volume of a cube represents the amount of space enclosed inside it.
It is calculated using the formula:

Volume = a³

where a is the length of one side of the cube.

This program asks the user to enter the side length of the cube, then computes and displays its volume.

C Program: Volume of a Cube

#include <stdio.h>
 
int main() {
    float side, volume;
 
    // Input side length of the cube
    printf("Enter the side length of the cube: ");
    scanf("%f", &side);
 
    // Calculate volume
    volume = side * side * side;
 
    // Display result
    printf("Volume of Cube = %.2f\n", volume);
 
    return 0;
}
    
 

 
OUTPUT 1 :
Enter the side length of the cube: 5
Volume of Cube = 125.00

OUTPUT 2 :
Enter the side length of the cube: 3.2
Volume of Cube = 32.77

Explanation

1. Input → The program takes the side length of the cube as input.
2. Process → It applies the formula side × side × side.
3. Output → The result is printed with two decimal places.
