If we’re going to use chips in that package, we need to spread that heat. Roughly speaking, we need to spread the heat from a 1cm2 area to a 80cm2, or a circle with a radius of 5cm2.
That's a factor of 80, how do you get 6400?

You're saying 80 cm^2 is 6400 times the area of 1 cm^2?

oh lol you're right. i read that as "1x1cm and 80x80cm" rather than 1 and 80 square centimeters. i don't know why i did that.

Good catch, I somehow glanced over it and in my mind did @k00b's (wrong) explanation below too.
