A line AB in 3D space is given. The projection of AB on the x, y, and z axes are 6, −3, and 2 respectively. The length of AB is: A. 5 B. 6 C. 7 D. 8 Answer: C) 7 Explanation: Length of projection on axes corresponds to the components of the vector AB. Length = √(6² + (−3)² + 2²) = √(36 + 9 + 4) = √49 = 7.
