Find the moment of inertia of the following "L" shape about the x-x axis (I sub x)

The base of the L shape is 4 inches long and 2 inches high.
The vertical column of the L shape is 8 inches high and 2 inches wide.

(So the "block L" is 2 inches wide vertically and horizontally. As stated, it's 8 inches high and has a 4 inch base along the bottom.)

The x-axis is sketched in about 2 1/2 inches up from the base/bottom of the L

Please help with the set up and how to solve. Thank you.
