Answer» 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 |
