C. 60 unit cubes.
Each level has 20 unit cubes, times 3 is 60 in total.
Answer:
35 degrees
Step-by-step explanation:
In this situation we will be using opposite/hypotenuse, as that is what is shown to us through SohCahToa.
Since we are trying to find the angle we will need to use arcsin.
arcsin(31/54)
the angle is 35 degrees

Trigonometric Identities.
To solve this problem, we need to keep in mind the following:
* The tangent function is negative in the quadrant II
* The cosine (and therefore the secant) function is negative in the quadrant II
* The tangent and the secant of any angle are related by the equation:
We are given:
And θ lies in the quadrant Ii.
Substituting in the identity:
Taking the square root and writing the negative sign for the secant:
Given the zeros of a polynomial, you can very easily write it -- first in its factored form and then in the standard form. Subtract the first zero from x and enclose it in parentheses. This is the first factor. For example if a polynomial has a zero that is -1, the corresponding factor is x - (-1) = x + 1.
