You haven't told us what the passing percentage is on the exam,

I’m lost at this question, sorry but I would’ve help !
A uniform thin solid door has height 2.20 m, width .870 m, and mass 23.0 kg. Find its moment of inertia for rotation on its hinges. Is any piece of data unnecessary? So far, I don't understand how to calculate moments of inertia for things like this at all.

so A
