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.

  2. //Java Program to Find the Surface Area and Volume of a Cuboid
  4. import;
  5. import;
  7. public class Cuboid {
  8.     // Function to calculate the Surface Area and Volume of a Cuboid
  9.     public static void main(String[] args) {
  10.         BufferedReader br = new BufferedReader(new InputStreamReader(;
  11.         double length,breadth,height;
  12.         System.out.println("Enter the length, breadth and height of the cuboid");
  13.         try{
  14.             length=Double.parseDouble(br.readLine());
  15.             breadth=Double.parseDouble(br.readLine());
  16.             height=Double.parseDouble(br.readLine());
  17.         }catch (Exception e){
  18.             System.out.println("An error occurred");
  19.             return;
  20.         }
  21.         if(length<=0 || breadth<=0 || height<=0){
  22.             System.out.println("Wrong Input");
  23.             return;
  24.         }
  25.         System.out.println("Volume = " + length*breadth*height);
  26.         System.out.println("Surface area = " + 
  27.                             2*(length*breadth + breadth*height + height*length));
  28.     }
  29. }
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):
Enter the length, breadth and height of the cuboid
Volume = 665.2416
Surface area = 481.4336
