Why is my model's mass different from the answer?

I have provided the question pdf and the two solidworks part files I made as answer. They are both different from the provided mass. Kindly check what's wrong with them.

Accepted answer

I can't check your file because it is from a future version. But I did the first part of the question and everything is correct. What difference in mass do you see?
