英文计算题 紧急~!
给出答案(要过程)或者翻译!
If one micrometeorite (a sphere with a diameter of 2.4 10^(-6) m) struck each square meter of the Moon each second, how many years would it take to cover the Moon to a depth of 1.0 m? (Hint: Consider a cubic box, 1.0 m on a side, on the Moon, and find how long it would take to fill the box.)

答案和解析
如果每秒钟都有一个小陨石(直径范围是 2.4 10^(-6) m)撞击月球表面的每一平方,那么请问,需要多少年月球表面才会被覆盖1米?
(提示:假设月球上有一个边长为1米方形的盒子,需要多久才能装满盒子)
