Question

Write a java program that computes the total surface area of a rectangular prism. There are six sides, so the area of all six sides has to the summed to get the total area. The program should ask the user to enter the length (L), width (W) and the height )H) for the object in inches. Create a separate method from the main to calculate the area (name the method calcArea). The output of calcArea will return a double. Output; The total area for the rectangular prisminches long, inches wide, and inches tall issquare inches. A must be formatted to two decimal places, using a printf statement.

code

  
import java.util.Scanner;
class ReatangularPrism {
private double length , width , height ;
private double area ;   
public ReatangularPrism(double length, double width, double height) {
this.length = length;
this.width = width;
this.height = height;
}
public double calcArea(){
System.out.printf(" long inches: %.2f", Double.valueOf(length) );
System.out.print("\n");
System.out.printf(" width inches: %.2f", Double.valueOf(width) );
System.out.print("\n");
System.out.printf(" tall balance : %.2f", Double.valueOf(height)); // this is for print value of 2 decimal according to you requirement
System.out.print("\n");
// formula to find the sufrace are aof rectangular prism prims it has size sides we are sum up as show below
area = (2 * (width * length)) +(2 * (length * height))+(2 * (length * width));
return area ;
}
}
public class Main1
{
public static void main(String[] args) {
Scanner scan = new Scanner(System.in) ;
double length , width , height ;
System.out.println("Enter Length : ");
length = Double.valueOf(scan.nextLine());
System.out.println("Enter width : ");
width = Double.valueOf(scan.nextLine());
System.out.println("Enter height : ");
height = Double.valueOf(scan.nextLine());
ReatangularPrism rec = new ReatangularPrism(length , width , height);
double area = rec.calcArea();
System.out.printf("\nTotal Surface area is : %.2f", Double.valueOf(area));}}
