First layer: you can put 4 cubes. These 4 cubes are not visible from the front and side since there are already cubes blocking their view.
For the second layer, you can only put 3 cubes.
2 of those cubes are right behind the rightmost cube on the 2nd layer (from the side view)
They will be blocked from both the side and front views.
1 of them is at the corner where the front and side views meet.
Total 7
You can't put anymore cubes as they will not be blocked and will be visible.
