    1Mg @ 19.8g/cc

    1000000/19.8=50505cc

    ³√50505 = 37cm

    So a little bigger than a cubic foot assuming you could prevent super-criticality somehow

      Based on the Wikipedia article, it’s $6,490,000/kg.

      Assuming you can legally purchase that amount (which you can’t), you could even find that much for sale (would you probably couldn’t), and the price didn’t go up as you purchased more of a very scarce resource (which it would), it would be about $6.5 billion US.

      Cool, though I would assume the supercritical point would be a lot higher for Pu-242. I can’t imagine that anyone would have knowingly sold this kid a fissile isotope.
