# Atomic E of a girl

If some girl weighs 100 pounds or 45.45 kg

E=mc$$^2$$

Energy = (45.45) x (3 x 10$$^8$$)$$^2$$

My answer was 4.9 x 10$$^1^8$$ J of E. But it's been a while and I'm not confident. Is that wrong?

thanks

That should be right. Why do you need to know? Are you planning to put the girl through nulcear fission...?

What are you doing? $$5^9$$?

I'll assume you made a mistake, the answer is $$4.0905 * 10^{18}$$.

Ok thanks, 4.9 x 10$$^1^8$$ J of E.

NO! 4.09 x $$10^{18}$$, that zero is a huge difference.
