# 9 : C Program to Calculate Volume of Cube

Check out the complete list of c-programs : C Program List

To calculate the volume of Cube you need to know the side of the cube.

Variables :

1. side : (Datatype int) : to represent the side a cube.

2. volume_of_cube : (Datatype long) : to store the volume of cude result.

Functions :

printf() : is used to display something on the console/screen. Format specifier %d in printf function is used to display a int variable on screen and %ld for long. \n is used to add a newline

scanf() : is used to fetch data inputted by the user on the console/screen using keyboard. %d in scanf is indicates that inputted text is of type int and %ld for long.

Formula :

Volume of Cube : (side)3

#include <stdio.h>
//#include <conio.h>

void main() {

int side;
long volume_of_cube;

//	clrscr();

printf(" Program to calculate Volume of a Cube :  \n\n");

printf(" Enter the side of cube : ");
scanf("%d", &side);

volume_of_cube = side*side*side;

printf("\n\n Volume of Cube with Side as %d = %ld ",side, volume_of_cube);

//	getch();

}
```
```

• Output :

Program to calculate Volume of a Cube :

Enter the side of cube : 40

Volume of Cube with Side as 40 = 64000

Program to calculate Volume of a Cube :

Enter the side of cube : 10

Volume of Cube with Side as 10 = 1000
