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

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

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?
