For this case we have:
Be a function of the form 
Where:

If we want to find f (-2), we substitute
, then:

Since we have a negative root, the result will be given by complex numbers. By definition:

So:

Answer:

1st : Find the volume of the rectangular block:
12 × 10 × 20 = 2400 cm^3.
2nd : Find the volume of a cylinder

Where r is radius & h is height.
so:

= 76.02654222 cm^3
Lastly, divide the volume of the rectangular block by the volume of the cylinder
2400 ÷ 76.026 = 31.5679226
You can't round it up so the answer is F) 31
