Find the length of the longest rod that canbe fitted into a rectangula – InterviewSolution

1.	Find the length of the longest rod that canbe fitted into a rectangular cuboidal box ofdimensions 6 dm (width), 8 dm (length) and7.5 dm (height).
Answer» Given length l = 8dmbreadth b = 6dm and height h =7.5dmLongest rod that can be placed in a room is nothing but its diagonal.Length of diagonal of a cuboid = √(l² + b² + h²)Length of longest rod = √(8²+ 6² + 7.5²) dm= √(64+ 36 + 56.25) dm= √156.25= 12.5dm
