Calvin is making a model Earth in his science class. The radius of the inner core of the model Earth is \(3\text{ cm}\) and the radius of the entire model Earth is \(18\text{ cm}.\) How many times larger is the volume of the entire model Earth than the volume of the inner core of the model Earth?

**Note:** Both the model Earth and its inner core are perfect spheres.
