# Coordinates of a centroind

Let’s A = [3, 2, 0], B = [1, -2, 4] and C = [1, 1, 1] be 3 points in space. Calculate the coordinates of the centroid of △ABC (the intersection of the medians).

Correct result:

x =  1.667
y =  0.333
z =  1.667

#### Solution:

$x_{0}=3 \ \\ y_{0}=2 \ \\ z_{0}=0 \ \\ \ \\ x_{1}=1 \ \\ y_{1}=-2 \ \\ z_{1}=4 \ \\ \ \\ x_{2}=1 \ \\ y_{2}=1 \ \\ z_{2}=1 \ \\ \ \\ x=\dfrac{ x_{0}+x_{1}+x_{2} }{ 3 }=\dfrac{ 3+1+1 }{ 3 }=\dfrac{ 5 }{ 3 }=1.667$
$y=\dfrac{ y_{0}+y_{1}+y_{2} }{ 3 }=\dfrac{ 2+(-2)+1 }{ 3 }=\dfrac{ 1 }{ 3 }=0.333$
$z=\dfrac{ z_{0}+z_{1}+z_{2} }{ 3 }=\dfrac{ 0+4+1 }{ 3 }=\dfrac{ 5 }{ 3 }=1.667$
