draw isometric view and side of this drawing?

It is more of an exercise in showing why multiple views are needed. Or why hidden lines are needed.
Without another view, or without hidden lines to show if a pocket exists, and its depth, I don't think you'll be able to determine the answer. A guess can be made, but why guess and waste time making the wrong part?
You should also ask what the dimensions are.

wrong answer dude, its not square, not rectangle

you will show hidden line in drawing then make part.
