Explanation:
Surface area is 54cm²
, volume is 27cm³
and surface area-to-volume ratio is 2
Explanation:
If s is the side of a cube, then its surface area is 6s²
and its volume is s³
Hence, if the sides of a cube are 3 inches long
its surface area is
6×3²
=6×9
=54cm²
,
its volume is 3³=27cm³
and surface area-to-volume ratio is
54/27=2

Explanation:
The correct answer is C. The burning of fossil fuels.
Explanation
The carbon cycle is a cycle in which carbon interacts with the biosphere, the lithosphere, the hydrosphere, and the Earth's atmosphere. Knowledge about this carbon circulation makes it possible to appreciate human intervention in the climate and its effects on climate change. This cycle makes life on Earth possible because the plants consume carbon dioxide, however, the balance of this cycle has been altered by the massive use of fossil fuels such as oil, gasoline, and gas. This alteration causes the atmosphere to deteriorate causing the sun's rays to directly penetrate the earth, on the other hand, it causes the greenhouse effect to increase, causing the earth's temperature to rise. So, the correct answer is C. The Burning of fossil fuels.
