This is a lab experiment? Then it is my
understanding you want to demonstrate that
the deflection is happening. Can you attatch
a travel indicator inside the vacuum vessel
to show the deflection in process? Then you
would vary the pressure outside the cube and
chart the deflection and acquire your own
data...
So in effect you will be making a pressure gauge
using the center of a wall of the cube as the
diaphram. Even a levered pointer with one end
resting on the wall, and the other reading at
a scale based on the leverage calculations
would prove the point. This would challange
and/or test known data and you would never
forget the results. So you take the modulus,
thickness,lengty. inside pressure, outside pressure
and your varying data and devise a formula
then test it against those already published.

... then perhaps some day you can design a better
deep sea submersable. ... "wink"
