Step-by-step explanation:
Using the volume of the rectangular prism, it is found that it takes 7 hours to fill the pool.
<h3>What is the volume of a rectangular prism?</h3>
The volume of a rectangular prism of dimensions l, w and h is given by the multiplication of it's dimensions, that is:
V = lwh.
In this problem, the dimensions in meters are: l = 7, w = 3, h = 0.75. Hence, the volume in cubic meters is:
V = lwh = 7(3)(0.75) = 15.75.
It fill 2.25 cubic meters per hour, hence, for 15.75 cubic meters, the time taken is:
15.75/2.25 = 7 hours.

The cosine of 30° is √3 / 2.
Since cosine is Adjacent over Hypotenuse, Hypotenuse = (2 / √3) * 9 = 18 / √3.
The cosine of 45° is √2 / 2.
Therefore, X = (2 / √2) * (18 / √3) = 36 / √6 = 18 / √1.5 = C
