Introduction

In this demo I have used NetBeans IDE 8.2 for debugging purpose. But you can use any java programming language compiler as per your availability..

import java.util.Scanner;
class TotalSurfaceAreaOfCuboid {
      
    public static void main(String args[]) 
    {         
    Scanner s= new Scanner(System.in);
        System.out.println("Enter the length of cubiod:");
        double l=s.nextDouble();

        System.out.println("Enter the breadth of cubiod:");
        double b=s.nextDouble();

        System.out.println("Enter height of cubiod:");
        double h=s.nextDouble();
   		 
        double  area=(2*((l*b)+(b*h)+(h*l))); 
        System.out.println("Total surface area Of cuboid is:" +area);   
          
    }
}

Result
