1.5 times the radius of Earth with a core that is 70% iron.
So, maybe on the order of 1 billion cubic miles of iron?
That's a whole lot of rebar and steel framed buildings.

That's a whole lot of rebar and steel framed buildings. Good luck taking off from such a planet with your payload. Assuming you survived the "landing".

What’s the total mass of iron?
Then work backwards to get the mass of hydrogen which must’ve fused to create it; then can we get an estimate of the mass of the star which originally created that planet?
