Question

What is the distance between # (4, 3, 1) `and`(3, 4, 1) #?

Answer 1

`d=sqrt((x_2-x_1)^2+(y_2-y_1)^2+(z_2-z_1)^2)`
`=sqrt((3-4)^2+(4-3)^2+(1-1)^2)=sqrt2`

Explanation:

The distance formula for calculating the distance between two points in 3D, `(x_1,y_1,z_1)` and `(x_2,y_2,z_2)` is as shown above.
