Which has the least? Provide an explanation and proof for your answer to receive full credit.

Answer 1

In order to calculate the population density, we need to divide the population by the area in each case.

So, calculating the density for each country, we have:

$\begin{gathered} U\text{.S:} \\ \frac{272648000}{9364520}=29.115 \\ \\ \text{Romania:} \\ \frac{22609000}{237391}=95.239 \\ \\ \text{Ghana:} \\ \frac{18339000}{237533}=77.206 \end{gathered}$

Therefore the greatest population density occurs at Romania, and the least occurs at U.S.
