Q2. 2. Shortest distance between 2 points on a 3d cubical surface
Ans. 
The shortest distance between 2 points on a 3D cubical surface can be calculated using the Manhattan distance formula.
• Calculate the absolute difference between the x, y, and z coordinates of the two points.

• Sum up the absolute differences to get the Manhattan distance.

• Manhattan distance = |x2 - x1| + |y2 - y1| + |z2 - z1|

• Example: If point A is (1, 2, 3) and point B is (4, 5, 6), the Manhattan distance would be |4-1| + |
