Answer:
<h2>The shelter can contain 512 cubic meters of water.</h2>
Step-by-step explanation:
This question can be translated to:
<em>
</em>
<em>"The manager of the drinking water service in my town creates a water tank in the highlands so that the water can reach the entire town. The cube-shaped shelter is 8 meters long. If the shelter is full, how many liters of water can it contain?"</em>

As you can observe, the volumetric form is a cube with 8 meters long each edge.
We know the volume of a cube is defined as
Where 
, replacing this value, we have
Therefore, the shelter can contain 512 cubic meters of water.
Finding the value of the second variable when the first variable is equal to one and then multiplying the second variable by the first variable of each answer will always work in this situation (two variable).
<span>First of all, there should be coherence for the units of measurement -- either they are all meters or they are all ft. I would assume they are all ft.
The correct answer is 75 ft above. T
The explanation is the following: suppose the ground level is the x-axis, the 2 feet of the arch lie respectively on (0,0) and (100,0) on the ground level. Since the arch is 100ft high, the vertex of the parabola will be the point (100,100). Thus, we can find the equation describing the parabola by putting the three points we know in a system and we find that the equation of the parabola is y=(-1/100)x^2+2
To find the focus F, we apply the formula for the focus of a vertical axis parabola, i.e. F(-b/2a;(1-b^2+4ac)/4a).
By substituting a=-1/100, b=2 and c=0 into the formula, we find that the coordinates of the focus F are (100,75).
So we conclude that the focus lies 75ft above ground.</span>
