What Mick showed us it was so easy but the challenge was quite tricky and I implemented it totally the other way round. First I went to right orthographic then moved the cube 1 unit in Z, then moved it 1 unit in y. Grabbed one of the edge and pulled it in z by 2 units.

Then grabbed another edge pulled it in y by 4 units.

And at last grabbed the edge which I pulled in y by 4 units and lowered it down by -2 units in the z. The whole model was bigger than mick’s model.

And this is the final result
