Answer 2

Answer:

 I ABOUT Z-- AXIS , PASSING THROUGH ONE CORNER

=mp²/12 + m4p²/12 = 5mp²/3                  

Explanation:

I=MOMENT OF INERTIA

I ABOUT X- AXIS , PASSING THROUGH ONE CORNER(ALONG LENGTH i.e bc. let ad = p , then bc=2p)= mp²/3

I ABOUT Y- AXIS , PASSING THROUGH ONE CORNER(ALONG LENGTH i.e AD) = 4mp²/3

 I ABOUT Z-- AXIS , PASSING THROUGH ONE CORNER

=mp²/12 + m4p²/12 = 5mp²/3                                                                    

I about COM ,x-axis=mp²/12 ,y-axis=4mp²/12 , z-axis=x+y=5mp²/12
