The distance is $sqrt179$

Either you do it using vectors or the distance betwwen two points.
If you have two points $(x_1,y_1,z_1)$ and $(x_2,y_2,z_2)$

The distance is $=sqrt((x_2-x_1)^2+(y_1-y_2)^2+(z_1-z_2)^2)$
The distance is $=sqrt(11^2+7^2+3^2)=sqrt(121+49+9)=sqrt179$

What is the distance between (-8,8,-1)(-8,8,-1) and (3,1,2)(3,1,2)?
