Calculating elastic modulus in a certain shape

How exactly would you calculate E in this? The cross section is a square and it deforms .8 mm. I'm not quite sure what to do since obviously the size of the cross section changes.

The elastic modulus is a property of the material and not the shape. Is this a square cross sectioned tapered column subject to axial load? Wood, steel, other?

Is this a homework problem?
