# C Program to find Volume and Surface Area of a Cube

How to write C Program to find Volume and Surface Area of a Cube with example?. Before we step into the C Program to find Volume and Surface Area of a Cube, Let see the definitions and formulas behind the Surface area of a Cube and Volume of a Cube.

## C CUBE

All the edges in the Cube have the same length. We can say, Cube is nothing but six equal squares.

### C Surface Area of a Cube

If we know the length of an edge in Cube, then we can calculate the surface area of a Cube using the formula:

• Surface Area of a Cube = 6l² (Where l is the length of any side of a Cube).
• Area of a square = l² Since the Cube made of 6 equal squares, Surface Area of a Cube = 6l²

If we already know the Surface Area of Cube and then we can calculate the length of any side by altering the above formula as:

• l = √sa / 6 (sa = Surface Area of a Cube)

### The Volume of a Cube in C

The amount of space inside the Cube called Volume. If we know the length of any edge of a Cube then we can calculate the Volume of Cube using the formula:

• Volume = l * l * l
• The Lateral Surface Area of a Cube = 4 * (l * l)

## C Program to find Volume and Surface Area of a Cube

This C program allows the user to enter any side of a Cube. By using this value, this C program will find the Surface Area of a cube, Volume of a cube, and Lateral Surface Area of a Cube as per the formulas.

```/* C Program to find Volume and Surface Area of a Cube */

#include

int main()
{
float l, SA,Volume, LSA;

printf("\n Please Enter Length of any side of a Cube \n");
scanf(" %f ", &l);

SA = 6 * (l * l);
Volume = l * l * l;
LSA = 4 * (l * l);

printf("\n Surface Area of Cube = %.2f", SA);
printf("\n Volume of cube = %.2f", Volume);
printf("\n Lateral Surface Area of Cube = %.2f", LSA);

return 0;
}```

In this C program, We entered the Length of any side of a Cube = 5

The Surface Area of a Cube is
Surface Area of a cube = 6 * length * length
Surface Area of a cube = 6 * 5 * 5
Surface Area of a cube = 150

The Volume of a Cube is
Volume of a cube = length * length * length
Volume of a cube = 5 * 5 * 5;
Volume of a cube = 125

The Lateral Surface Area of a Cube is
Lateral Surface Area of a cube = 4 * length * length
Lateral Surface Area of a cube = 4 * 5 * 5
Lateral Surface Area of a cube = 100

In the above C Programming example, we got the Surface area of a cube = 150 when the length = 5. Let us make the reverse approach (calculate the length of a Cube using Surface Area = 150)

Length of a cube = √sa / 6
Length of a cube = √150 / 6
Length of a cube = √25
Length of a cube = 5
