Consider this Java class:
```java
public class ShippingBox {
private int length;
private int width;
private int height;
private int volume;
public ShippingBox(int side) {
this(side, side, side);
}
public ShippingBox(int length, int width, int height) {
this.length = length;
this.width = width;
this.height = height;
volume = length * width * height;
}
}
```
Which state results from `ShippingBox b = new ShippingBox(3);`?
