The volume of the Moon is about 2.18*10^10 cubic kilometers. The volume of Earth is about 1.09 cubic kilometers. The number of Moons that can fit inside Earth can be found by dividing Earth's volume by the Moon's volume. About how many Moons can fit inside Earth?
A) 50
B) 200
C) 100
D) 500
C) 100
To find the number of Moons that can fit inside Earth, divide Earth's volume by the Moon's volume:
1.09 cubic kilometers / 2.18*10^10 cubic kilometers ≈ 100
Therefore, about 100 Moons can fit inside Earth.
