    Ok, I already have that comets alltogether add 5.969646 e 20 ml in the 4 million years. So to find the percent I should divide this quantity by 1.36 billion km3 (what earth's oceans occupy. But how do I convert ml to km3 in order to perform the calculation

    Look, I already tried it and I DO listen in class, the problem is that we never really see how to solve problems like this. This problem in particular is an extra credit one. Just tell me if the answer is .044 %

    HI! I am new to this forums and this is my first post. Look, I have a homework problem that I hope you guys know how to figure it out. Here it is: Recently, Dr, Frank has suggested that EArth may be pelted by thousands of house-sized comets. When Frank first considered the idea of mini-comets falling to earh , he no doubt tried to make a quick calculation. Comets are like dirty snowballs that evaporate when they enter the atmosphere. Oceans have accumulated from these comets over the years. Use the following information to estimate what percent of Earth's oceans could be accounted for givena constant bombardment by comets over the last 4 million years: 1 year=365.25 days 1 ton=2000 lbs 1 pound = 454 grams Density of water = 1g/ml 15000 minicomets hit earth every day Earth's oceans occupy 1.36 billion km3 1 mini comet = 30 tons Help is greatly appreciated, thanks
