C Program to Find Volume of Cuboid

by

Howdy readers, today you will learn how to find the volume of a cuboid using the C Programming language.

C Program to Find Volume of Cuboid

A cuboid is a three-dimensional shape that has 6 faces, 12 edges, and 8 vertices. It is different from a cube since all the faces of a cuboid are rectangular in shape, whereas a cube has square faces. 

To calculate the volume of a cuboid we find the product of its length, breadth and height. It is given by the formula:

  • Volume = Length x Breadth x Height

You can use any of the following methods to find the volume of a cuboid:

  1. Using Standard Method
  2. Using User-defined Functions

So, without any delay, let’s begin this tutorial.

C Program to Find Volume of Cuboid

C Program

// C Program to Find the Volume of a Cuboid
#include <stdio.h>
int main(){
    float length, breadth, height;
    float vol;
    
    // Taking input
    printf("Enter the length: ");
    scanf("%f", &length);
    printf("Enter the breadth: ");
    scanf("%f", &breadth);
    printf("Enter the height: ");
    scanf("%f", &height);
    
    // Computing volume
    vol = length * breadth * height;
    
    // Display result
    printf("The volume of the cuboid is: %.2f", vol);
    
    return 0;
}

Output

Enter the length: 9
Enter the breadth: 6
Enter the height: 15
The volume of the cuboid is: 810.00

Explanation

    // Computing volume
    vol = length * breadth * height;

The volume of the cuboid is calculated using the mathematical formula: Volume of Cuboid = Length x Breadth x Height.

The volume gets stored in the vol named variable.

    printf("The volume of the cuboid is: %.2f", vol);

The volume of the cuboid is printed on the screen with the help of the printf() function. The %.2f format specifier is used to limit the value of volume to 2 decimal places.

C Program to Find Volume of Cuboid Using Function

C Program

// C Program to Find Volume of Cuboid Using Function
#include <stdio.h>

// Defining function
float volume(float l, float b, float h){
    return (l * b * h);
}

int main(){
    float length, breadth, height;
    float vol;
    
    // Taking input
    printf("Enter the length of the cuboid: ");
    scanf("%f", &length);
    printf("Enter the breadth of the cuboid: ");
    scanf("%f", &breadth);
    printf("Enter the height of the cuboid: ");
    scanf("%f", &height);
    
    // Calling out function
    vol = volume(length, breadth, height);
    
    // Display result
    printf("The volume of the cuboid is: %.2f", vol);
    
    return 0;
}

Output

Enter the length of the cuboid: 2
Enter the breadth of the cuboid: 4
Enter the height of the cuboid: 6
The volume of the cuboid is: 48.00
C Program to Find Volume of Cuboid Using Function

Explanation

float volume(float l, float b, float h){
    return (l * b * h);
}

We have defined a user-defined function named volume which passes the dimensions of the cuboid as arguments and returns the volume of the cuboid.

    // Calling out function
    vol = volume(length, breadth, height);

Then, this function is called out in the main function which gives the value of the volume. The returned value gets stored in the vol named variable.

Conclusion

Today you learned how to find the volume of a cuboid in the C Programming language.

You can use any of the approaches to find the volume of the cuboid. The standard method sounds more simple and easy to me.  Let me know which one you like more.
