Hurry. the habitable part of earth's surface has been estimated to cover 60 trillion square meters. estimate the percent of this area occupied by humans if earth's current population stood packed together as people do in a crowded elevator. include all the work leading to the answer.

The current population is about 7.6 billion. if all of us could stand packed together shoulder to shoulder, we would require an area of about:

7.6 billion multiplied by area required by each person to stand.

On an average, area required per person to stand would be approximately 0.4 .

area occupied by 7.6 billion people = 7600000000 ×0.4

=30.4×

in percentage, area occupied by population standing together to the current habitable area = ×100%=0.005%.

the answer is 12 as i may remember
