To calculate the population of the country, you can use the formula:
\[ \text{Population} = \text{Population Density} \times \text{Area} \]
Given:
- Population Density = 120 people per square mile
- Area = 76,254.89 square miles
Now, substitute the values into the formula:
\[ \text{Population} = 120 , \text{people/mi}^2 \times 76,254.89 , \text{mi}^2 \]
Now, perform the multiplication:
\[ \text{Population} = 120 \times 76,254.89 \approx 9,150,586.68 \]
Rounding off gives us approximately 9,150,586 people.
Therefore, the correct answer is 9,150,586 people.
