Average amount of carbon stored in 1 sq kilometer if there is 547.8 gigatonnes of carbon in 22.6 million km squared

Average amount of carbon per km² = 24.238 kilo tonnes per km²

Explanation:
We know that the average amount of carbon in 22.6 million km² is 547.8 gigatonnes. To know the average amount of carbon in 1 km², all we have to do is cross multiplication as follows:
1 km² > ?? carbon
22.6 million km² > 547.8 gigatonnes of carbon
Average amount of carbon per km² = (547.8 * 10^9 *1) / (22.6 * 10^6)
Average amount of carbon per km² = 24.238 kilo tonnes per km²

Hope this helps :)
