The distance between $(0,0,8)$ and $(4,3,1)$ is $8.6023$

The distance between two points $(x _1,y_1,z_1)$ and $(x _2,y_2,z_2)$ is given by

$sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)$ .

Hence distance between $(0,0,8)$ and $(4,3,1)$ is

$sqrt((4-0)^2+(3-0)^2+(1-8)^2)$

= $sqrt(4^2+3^2+(-7)^2)$

= $sqrt(16+9+49)$

= $sqrt74=8.6023$

What is the distance between (0, 0, 8) (0, 0, 8) and (4, 3, 1) (4, 3, 1) ?
