Find the length of the longest pole that can be placed in a room which is 24 m long, 16 m broad and 18 m high.1). 27 m2). 19 m3). 34 m4). 23 m

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
