1. The problem statement, all variables and given/known data

How many earths would fit inside the sun?

2. Relevant equations

3. The attempt at a solution

I found the volume of the sun and the earth (Using the sphere volume formula) and devided the sun's volume by the earth and got 10^6.....I was wondering whether this is the best solution

The density of the most efficient sphere packing is

$$\frac{\pi}{\sqrt{12}} \approx 0.9069$$
