A box is a three-dimensional object with width, height, and depth.

Complete the following file:

Box.java

public class Box { private double height; private double width; private double depth; /** Constructs a box with a given side length. @param sideLength the length of each side */ public Box(double h, double w, double d) { // your work here } /** Gets the volume of this box. @return the volume */ public double volume() { // your work here } /** Gets the surface area of this box. @return the surface area */ public double surfaceArea() { // your work here } }

Use the following file:

BoxTester.java

public class BoxTester
{
   public static void main(String[] args)
   {
      Box myBox = new Box(10, 10, 10);
      System.out.println(myBox.volume());
      System.out.println("Expected: 1000");
      System.out.println(myBox.surfaceArea());
      System.out.println("Expected: 600");      
      myBox = new Box(10, 20, 30);
      System.out.println(myBox.volume());
      System.out.println("Expected: 6000");
      System.out.println(myBox.surfaceArea());
      System.out.println("Expected: 2200");      
   }
}
