A solid rectangular object having dimensions of l = 4.00 cm, w = 3.00 cm, and h = 1.00 cm is subjected to a compressive stress having a force of F = 2.00×10⁵ N applied perpendicularly on the right and left faces of the rectangular object.

If this force was instead applied on the upper and lower faces on the rectangular object without changing the direction of the force (Figure B), by how much distance would the upper face be deformed with respect to the lower face of the rectangular object?
