If one micrometeorite (a sphere with a diameter of 1.0 ✕ 10-6) struck each square meter of the moon each second, it would take many years to cover the moon with micrometeorites to a depth of 1.9 m. consider a cubic box, 1.9 m on a side, on the moon. estimate how long it would take to completely fill the box with micrometeorites if one micrometeorite landed in the box each second.
