Question

the volume of the moon is about 2.18×10^10 cubic kilometers. the volume of earth is about 1.09×10^12 cubic kilometers. the number of moons that can fit inside earth can be found by dividing earths volume by the moons volume. about how many moons can fit inside earth? 50 100 200 500

Explanation:

Step1: Identify volume values

Volume of Earth $V_E=1.09\times 10^{12}$ cubic - kilometers, volume of Moon $V_M = 2.18\times 10^{10}$ cubic - kilometers.

Step2: Calculate the number of Moons

Use the formula $n=\frac{V_E}{V_M}$, so $n=\frac{1.09\times 10^{12}}{2.18\times 10^{10}}$.

Step3: Simplify the expression

Using the rule of exponents $\frac{a^m}{a^n}=a^{m - n}$, we have $\frac{1.09}{2.18}\times10^{12 - 10}=0.5\times10^{2}=50$.

Answer:
