In the attached document, my actual value of the cube root and also my estimated value come out the same. Can someone please take a look at my script?

Look at your code:
fprintf('The actual cube root is %0.3f\n', Estimate)
fprintf('The estimate of the cube root is %0.3f\n', Estimate)
You are printing the same value twice. You never calculate the "actual" cube root.
Even if you did calculate the actual cube root, would you be able to see the difference within the 3 decimal places that you print out?

So the two values would be the same

No. Try with 1E-21 for example.
