Given that,
Dimensions of room are 24 m long, 16 m broad and 18 m high.
The longest rod that can be placed in a room has length equal to the diagonal of the room.
We know that diagonal of cuboid = √(length2 + breadth2 + height2)
Length of the longest pole = √(242 + 162 + 182) = √(576 + 256 + 324)= √1156 = 34 m
