Question

The volume of the Moon is about 2.18x10^10 ubic kilometers. The volume of Earth is about 1.09x10^12
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?

Answer 1

Divide the volumes: (1.09×10^12) / (2.18×10^10) = (1.09/2.18)×10^(12−10) = 0.5×10^2 = 50.

So about 50 Moons could fit inside Earth.
