The distance between 2 points $\left(x1,y1,z1\right)\phantom{\rule{1ex}{0ex}}\text{and}\phantom{\rule{1ex}{0ex}}\left(x2,y2,z2\right)$ =
$\sqrt{{\left(x2-x1\right)}^{2}+{\left(y2-y1\right)}^{2}+{\left(z2-z1\right)}^{2}}$
So, the distance between $\left(3,2,1\right)\phantom{\rule{1ex}{0ex}}\text{and}\phantom{\rule{1ex}{0ex}}\left(-1,4,-2\right)$ =
$\sqrt{{\left(-1-3\right)}^{2}+{\left(4-2\right)}^{2}+{\left(-2-1\right)}^{2}}$
$\sqrt{29}$
