3D Distance Formula
The distance between two points $(x_1, y_1, z_1)$ and $(x_2, y_2, z_2)$ in 3-dimensional space is calculated using:
$d = √{(x_2 - x_1)^2 + (y_2 - y_1)^2 + (z_2 - z_1)^2}$
Example:
Find the distance between points $(1, 2, 3)$ and $(4, 6, 8)$:
$d = √{(4-1)^2 + (6-2)^2 + (8-3)^2} = √{9 + 16 + 25} = √{50} = 7.07$
