Four same homogenious bricks are stacked on top of each other as illustrated below. They all have the horisontal sidelength of ”a”. The bricks are not rotated in comparison to each other. What is the maximum value of the distance ”d” that possibly can be achieved?

I am aware that the question obviously has to do with balancing the forces. The best answer of mine is d=15*a/16. The correct answer is d=11*a/12. I need help with deriving the correct answer.
