Answer 1

Answer:

Answer. Given length l = 12 m breadth b = 9 m and height h = 8 m Longest 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 = √(122 + 92 + 82) m = √(144 + 81 + 64) m = √289 m = 17 m Thus the length of the longest rod is 17 m
