Find the length of the longest rod that can be placed in room 12 m wide and 8 m high.Submitted on 23/12/2023 | Answered by Vandana Rana

Given that: length l=12m breadth b=9m and height h=8m
Longest rof that can be placed in a room is nothing but its diagonal.


 Length of diagonal of a cuboid =√(l² +b²+h²2) 

Length of longest rod =√(12²+9²+8²)m  

=√(144+81+64)m  

=√289 m 

= 17m

The length of the longest rod is 17 m .
