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[tex] m^{2} [/tex] .
area occupied by 7.6 billion people = 7600000000 ×0.4 [tex] m^{2} [/tex]
=30.4×[tex] 10^{8} [/tex] [tex] m^{2} [/tex]
in percentage, area occupied by population standing together to the current habitable area = [tex] \frac{3040000000}{60000000000000} [/tex]×100%=0.005%.
