Question

Write a program to calculate the area and circumference of a cuboid.

Use printf to display 2 digits after decimal point in all the results

Program should be in java language.

Answer 1

Code

import java.util.*;
import java.lang.*;
import java.io.*;
class T
{
   public static void main (String[] args) throws java.lang.Exception
   {
       Scanner in= new Scanner(System.in);
       float l,b,h;
       System.out.println( "Enter values of length");
       l=in.nextFloat(); //input length
       System.out.println( "Enter values of breadth ");
       b=in.nextFloat(); //input bradth
       System.out.println( "Enter values of height");
       h=in.nextFloat(); //input height
       float A,C;
       A=2*(l*b +b*h + h*l); //calculate surface area
       C=4*(l+b+h); //calculate circumference
       System.out.printf("Area of cuboid is %.2f \n", A);
       System.out.printf("Circumference of cuboid is %.2f \n", C);
   }
}
