Astronomy question about comets

I am stuck on this one question on my science homework, and I would like to know how to answer it so I can be ready for a quiz, too. Please help.
 
Suppose a comet passes the sun every 57 years, and it loses 8000 m3 of ice and rock each time. If the last time this comet was seen was in 1965, and it had a mass of 400,000 m3, in what year will the comet have passed the sun 3 more times, and how massive would it be then?
