Answer:
The answer would be B, or the second option.
Explanation:
To find the volume, you must multiply the length, width, and height of the object. (Length x Width x Height)
l × w × h
Replace each of the following variables with the length of each side. In this case, they are all 3, but remember that it doesn't matter in which order you put them in.
3 × 3 × 3.
Now multiply!
3 × 3 × 3 = 27 cubic feet.
Meaning, the final answer would be B.
