$50$ moons can fit inside Earth.

#### Explanation:

Volume of Earth is $1.09 \times {10}^{12}$ cubic kilometers

Volume of Moon is $2.18 \times {10}^{10}$ cubic kilometers

Hence number of Moons that can fit in Earth is

(1.09xx10^12)/(2.18xx10^10

= ${10}^{12 - 10} / 2$ $\text{ }$ as $\text{ } 2.18 = 1.09 \times 2$

= ${10}^{2} / 2$

= $\frac{100}{2} = 50$
