Java Program to Find Volume and Surface Area of Cuboids

This is the Java Program to Find the Surface Area and Volume of a Cuboid.

Problem Description

Given the dimensions of a cuboid, find out its surface area and volume.

Problem Solution

The surface area and volume of a cuboid can be calculated using the formulas:

Surface Area = 2*(length*breadth + breadth*height + height*length).
Volume = length * breadth * height.

Program/Source Code

Here is the source code of the Java Program to Find the Surface Area and Volume of a Cuboid. The program is successfully compiled and tested using IDE IntelliJ Idea in Windows 7. The program output is also shown below.

//Java Program to Find the Surface Area and Volume of a Cuboid

```
 
```
```
import java.io.BufferedReader;
```
```
import java.io.InputStreamReader;
```
```
 
```
```
public class Cuboid {
```

    // Function to calculate the Surface Area and Volume of a Cuboid

    public static void main(String[] args) {

        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));

```
        double length,breadth,height;
```

        System.out.println("Enter the length, breadth and height of the cuboid");

```
        try{
```

            length=Double.parseDouble(br.readLine());

            breadth=Double.parseDouble(br.readLine());

            height=Double.parseDouble(br.readLine());

```
        }catch (Exception e){
```

            System.out.println("An error occurred");

```
            return;
```
```
        }
```

        if(length<=0 || breadth<=0 || height<=0){

            System.out.println("Wrong Input");

```
            return;
```
```
        }
```

        System.out.println("Volume = " + length*breadth*height);

        System.out.println("Surface area = " +

                            2*(length*breadth + breadth*height + height*length));

```
    }
```
```
}
```

Program Explanation

1. In function main(), first, the length, breadth and height of the cuboid are taken as input.
2. The condition if(length<=0 || height<=0 || breadth<=0) checks if the input is valid or not.
3. The print statement displays the surface area and volume of the cuboid.

Time Complexity: O(1)

Runtime Test Cases

 
Case 1 (Simple Test Case):
