The distance between two points P ( x 1 , y 1 , z 1 ) and
Q ( x 2 , y 2 , z 2 ) in xyz-space is given by formula,
D = ( x 2 - x 1 ) 2 + ( y 2 - y 1 ) 2 + ( z 2 - z 1 ) 2
D ( P , Q ) = ( - 1 - 2 ) 2 + ( 4 - 0 ) 2 + ( - 2 + 1 ) 2
D ( P , Q ) = 9 + 16 + 1 = 26
Distance between ( 2 , 0 , - 1 ) and ( - 1 , 4 , - 2 ) is 26
