I don't know if anyone's gonna run out & grab a ruler for you
, but I will advise that it's relatively easy to run cabling to/from the rear center console. You would cut a hole an the back of the console, grommet any wires you run to/from the cube, and the wires would run out of the console, below the upper seat cushion/to the rear of the bottom cushion, then up and over into the trunk to grab power right at the battery.
Good luck!
