Four particles $($all having the same mass $=0\mathrm{.}32$ kg each$)$ are located at the corners of a square with side length $1\mathrm{.}06$ m $.$ The particles are held in place by thin rods whose mass can be ignored.

What is the rotational inertia of this rigid structure about an axis that passes through the midpoints of opposite sides and is in the plane of the square $($as in the first figure$)?$

$I=$

$kg*m^2$

Figure for first question:

What is the rotational inertia of this rigid structure about an axis that passes through one of the midpoints of an edge and is perpendicular to the plane of the square $($as in the figure below$)?$

$I=$

$kg*m^2$
