<em>Answer</em>
Denmark has the greatest population density
Ghana has the least population density
<em>Step-by-step explanation</em>
To find the population density we have to divide the population of each country by its area, as follows:
Given : Volume of the box = 10 gallons [gal].
One side of the box = 2.4 meters [m]
Another side of the box = 2.4 feet [ft].
To find : Length of third side in inches.
Soltution: We have to find the length of third side in inches.
So, we need convert all units in inches first.
1 gallon = 231 in^3.
Therefore, Volume = 10 gallons= 10* 231 = 2310 in^3.
1 meter = 39.3701 inches.
Therefore, one side of the box = 2.4 * 39.3701 = 94.48824 inches.
1 foot = 12 inches
Therefore, another side of the box = 2.4 feet = 12 * 2.4 = 28.8 inches.
We know formula for Volume of the box is given by
V = first side × second side × Third side
Plugging values in above formula.
2310 = 94.48824 × 28.8 × Third side.
On multiplying 94.48824 × 28.8 , we get
2310 = 2721.261312 × Third side.
Dividing both sides by 2721.261312, we get
Third side ≈ 0.85 (approximately)
