i'm having a hard time to project the missing top view and the isometric projection. My professor did not give me any information about what angle it is (like third angle or first angle), so I'm super confused on how to draw it:(
Since this is a homework question we won't give you a direct answer but instead, lead you through the steps to visualise and draw the solution.

Then do this:
Now which is the more likely projection?
Can you fill in the missing view? Edit your post to include your solution.
third angle or first angle ...
If faced with uncertainty like this in an assignment or exam I would provide both. If pressed for time I would provide one and state my assumption regarding the projection standard.
OK. Your cuboid is correct. You're just missing the diagonal.
Figure 3. A hint.
- Look at the red circle at the top of the diagonal. This means that the top of the diagonal must be somewhere along the red line on the isometric.
- Similarly the same point viewed on the other view (circled in green) must be somewhere on the green line.
Now what point could be on both lines simultaneously?
Can you do the same operation for the bottom of the diagonal?
Update the sketch when you've got that sorted and add it into your question (but leave the existing ones so that future readers can see the thought process).
