Answer:
Water is a human necessity. Therefore, it is one of the first things a human settlement would need to have. A community cannot thrive without a water source.

What does density mean?
- The density of an area refers to the quantity of things—which may include people, animals, plants, or objects—there are in it.
- Divide the number of objects by the area's measurement to determine density.
- A country's population density is calculated by dividing its total population by its area, expressed in square kilometers or miles.
We can calculate the volume of the cube by cubing the side of the cube.
Volume of cube = ( 1.000 cm)³
= 1.000 cm³
We can now determine the amount of lead in the cube by multiplying by the density. Because we know we have a 1.000 cubic centimeter and that lead has a density of 11.35 grams per cubic centimeter, we have 11.35 grams of lead.
= ( 1.000 cm³) ( 11.35
)
= 11.35 g

Hope this helps!
Below are the choices:
a)0.2168 atm
<span>b)4.613 atm </span>
<span>c)34.60 atm </span>
<span>d467.4 atm
</span>
1 atm = 760mmHg : Therefore:
<span>3,506mmHg = 3,506/760 = 4.613 atm
</span>B is correct answer.
