<em>The program is self explanatory; hence, no comments was used; However, see explanation section for line by line explanation.</em>
<em>Program starts here</em>
length = float(input("Length of small cube: "))
volume = 27 * length**3
print("Volume: "+(str(volume)))
Explanation:
The first line of the program prompts the user for the length of the small cube;
length = float(input("Length of small cube: "))
The volume of the 27 identical cubes is calculated on the next line;
volume = 27 * length**3
Lastly, the calculated volume of the 27 cubes is printed
print("Volume: "+(str(volume)))
Correctness is key. The other ones are optimizations at most. Although I would always include humor... ;-)
