Question

I have this project where I create a program that calculates the area of a rectangular prism. I am suppose to print the results in printf this is what I have... is it correct?

 

instructions ;

Write a Java program that computes the total surface area of a rectangular prism like the one below. There
are six sides, so the area of all sides has to be summed to get total area.
Inputs: The program should ask the user to enter the length (L), width (W), and height (H) for the object in
inches. So there are three inputs to the program.
Create a separate method from main to calculate the area.
Name the separate method calcArea and it needs to have three input arguments: length, width,
and height. The output of calcArea will return a double.
Outputs: The program should have this output (below is an example):
The total area for a rectangle prism <L> inches long, <W> inches wide, and <H> inches tall is <A> square
inches.
Where A is the area your program calculates and must be formatted to two decimal places, e.g. 12.48,
using a printf statement.
 
Does it mean that they all have to be printf or just the results?
 

import java.util.Scanner;

public class Chapter6ProjectFirstTry 

{

public static void main(String[] args) 

{

Scanner input = new Scanner(System.in);

System.out.print("Enter the Length: ");

double length =input.nextInt();

System.out.print("Enter the Width: ");

double width = input.nextInt();

System.out.print("Enter the Height: ");

double height = input.nextInt();

double total = 2*(length * width)+2*(height*length)+2*(height*width);

System.out.print%f("The total Surface area for the rectangle prism is " +length+ " inches long, " +width+ " inches wide, and  " +height+ " inches tall " + total + " square inches. ");

}

}

 

Thank you
