# C++ Exercises: Calculate the volume of a cube

## C++ Basic: Exercise-15 with Solution

Write a C++ program that calculates the volume of a cube.

Visual Presentation:

Sample Solution:

C++ Code :

#include <iostream> // Including the input-output stream header file

using namespace std; // Using the standard namespace

int main() // Start of the main function
{
int sid1; // Declaring an integer variable sid1 to store the side length of the cube
float volcu; // Declaring a floating-point variable volcu to store the volume of the cube
cout << "\n\n Calculate the volume of a cube :\n"; // Outputting a message indicating the calculation of cube volume
cout << "---------------------------------------\n"; // Outputting a separator line

cout << " Input the side of a cube : "; // Prompting the user to input the side length of the cube
cin >> sid1; // Taking input for the side length from the user

// Calculating the volume of the cube using the formula: side * side * side
volcu = (sid1 * sid1 * sid1);

cout << " The volume of a cube is : "<< volcu << endl; // Displaying the calculated volume of the cube
cout << endl; // Outputting a blank line for better readability

return 0; // Returning 0 to indicate successful program execution
} // End of the main function

Sample Output:

Calculate the volume of a cube :
---------------------------------------
Input the side of a cube : 5
The volume of a cube is : 125
