Suppose that a scientist estimates that every square mile of the ocean contains an
average of 4.6 × 104
pieces of trash. The area of the Earth’s surface that is
covered by oceans is approximately 1.2 × 108
square miles. Using the estimate,
how many pieces of trash are in the Earth’s oceans?

There are approximately 5.52 x 1012 pieces of trash in Earth's oceans. This is calculated by multiplying 4.6 x 104 pieces of trash per square mile by the area of the Earth's surface covered by oceans, which is 1.2 x 108 square miles. 5.52 x 1012 pieces of trash is the estimated total number of pieces of trash in the Earth's oceans.
