The scalar distance between two points can be found by:

sqrt( (x2 - x1)^2 + (y2 - y1)^2 + (z2 - z1)^2 )

where <x1, y1, z1> is your first point, and <x2, y2, z2> is your second
point.

So, in your example:

sqrt( (7 - 2)^2 + (-8 - 3)^2 + (3 - 4)^2 )

= sqrt( 5^2 + (-5)^2 + (-1)^2 )

= sqrt( 25 + 25 + 1)

= sqrt(51)

= 7.14 (approximately)
