please help me solve this :there are 10 million bacteria per square centimeter of coral in a coral reef.
The coral reef covers 18,000 km%5E2. How many bacteria are there in the coral reef?
----------------------------------------------------------

10%5E7 bacteria per cm%5E2.

10%5E7.10%5E4 = 10%5E11 bacteria per m%5E2.

10%5E11.10%5E6 = 10%5E17 bacteria per km%5E2.

Now multiply this number 10%5E17 by 18,000.
