Answer to Question #210778 in Mechanics | Relativity for Hailey

Question

Find the length of a side of a cube having a mass of 3.2 kg and the density of nuclear matter. 

Answer 1

take the density of nuclear matter$=2.3\times 10^{17}kg/m^3$

$volume, V=\frac{mass}{density}=\frac{3.2}{2.3\times 10^{17}}=1.39\times 10^{-17}m^3$

$l=({1.39\times 10^{-17}})^{1/3}=2.405\times 10^{-6}m$
