Question

Given dimensions of the room are 24 cm in breadth, 30 cm in height and 18 cm in length. Find the length of the longest pole that can be placed in the room

  1. 6306.56 
  2. 6366.56
  3. 6360.56
  4. 6300.56

hintHint:

 The formula for the diagonal of a cuboid is =

The correct answer is: 6306.56


    We have given the dimensions of room
    Length l =18 cm
    Breadth b = 24cm
    Height h = 30cm
    To find the length of the longest pole that can be placed in the room
    We have formula = square root of open parentheses l squared plus b squared plus h squared close parentheses end root
    square root of 18 squared plus 24 squared plus 30 squared end root
    square root of 324 plus 576 plus 900 end root
    square root of 1800
    30 square root of 2
    = 42.426 cm
