The population density in the United States is D = 92.1 people/mi^2

How to get the population density?</h3>
To get the population density, we need to take the quotient between the total number of people and the area.
In this case, we know that the total population is 325.7 million, and the area of the United States is 3,535,932 mi^2
Then the population density:
D = (325.7 million)/( 3,535,932 mi^2) = 9.21*10⁻⁵ million/mi^2
And we know that 1 million = 1,000,000 = 1*10⁶
Then:
9.21*10⁻⁵ million/mi^2 = 9.21*10¹ people/mi^2 = 92.1 people/mi^2
This means that in each square mile in the United States, there are around 92.1 people.

The cooler measurement should be measured in cm cubed, because you are finding the volume, which is three dimensional. The volume of the figure is 180 cm cubed. If you multiply the width, length, and height of the top object you get 36. When you add that to the volume of the bottom one (144) you get 180 cm cubed.
