I need help to prove that the moment of inertia of a uniform square of mass m and side d about an axis through its centre, parallel to a side is 1/12 md²

OK, what kind of help ? You know the definition of moment of inertia ? It amounts to an integration; does that pose a problem ? Write it out and we'll help you further.

Good you know it. Write down the integral and attempt to do the integration in your next post. The outcome of your calculation is your 'proof'.
