Calculate the average density of earth in terms of g, G and R.

Explanation

To calculate the average density of Earth in terms of \( g \), \( G \), and \( R \), we can follow these steps:

### Step 1: Understand the formula for density
The average density (\( \rho \)) of an object is defined as the mass (\( M \)) of the object divided by its volume (\( V \)):
\[ \rho = \frac{M}{V} \]
