every square mile of the ocean contains an average of 4.6*10^4 pieces of trash. the area of the earth's surface that is covered by oceans is approximately 1.2*10^8 square miles. how many pieces of trash are in the earth's oceans?
46000*120000000 = 5520000000000 or 4.6*10^4= 46000
If you are finding the area of something all you need to do is multiply 46000 by 1.2*10^81.2*10^(8 = 120,000,000
The answer would be 46000*120000000= 5.52*10^12
