    Answer: (2) 10 sqrt.2
    Explanation:-
    Given-
    Dimensions of the room = 10 cm x 8 cm x 6 cm
    Formula-
    The maximum length of rod that can be kept in a room = (length2 + width2 + height2)1/2
    Then, The maximum length of rod that can be kept in a room = (102 + 82 + 62)1/2
     = (100 + 64 + 36)1/2
    = (200)1/2
     = 10 (2)1/2
    Hence, the answer is (2) 10 sqrt.2.
