  • Q1. What is the shortest distance between two farthest vertices in a cubical room
  • Ans. 

    The shortest distance between two farthest vertices in a cubical room is the length of the diagonal of the cube.

    • The diagonal of a cube can be calculated using the formula: sqrt(3) * side length

    • In a cube with side length 1 unit, the diagonal length is sqrt(3) units

    • Therefore, the shortest distance between two farthest vertices in a cubical room is sqrt(3) times the side length of the cube
