Question

What is the distance between points A(1,1,1) and B (4,7,3)?

Answer 1

you should square root  [ (Xb-Xa)^2 + (Yb-Ya)^2 + (Zb-Za)^2 ]

it will look like this sqrt[ (4-1)^2 + (7-1)^2 +  (3-1)^2 ]

Answer 2

7 is correct. Use the Pythagorean theorem, which works in 3D spaces as well as 2D planes. a^2 + b^2 + c^2 = d^2.

Answer 3

X^2 = a^2 + b^2 + c^2

X = (9 + 36 +4)^-2

X = 7
