Question

    A cuboid has dimensions of 15 cm in length, 12 cm in

    breadth, and 9 cm in height. What is the length of its body diagonal?
    A 15√2 cm Correct Answer Incorrect Answer
    B 12√2 cm Correct Answer Incorrect Answer
    C 5√12 cm Correct Answer Incorrect Answer
    D 8√12 cm Correct Answer Incorrect Answer

    Solution

    We know that length of body diagonal of cuboid = √(length 2  + breadth 2  + height 2 )

    So, length of the body diagonal = √(15 2  + 12 2  + 9 2 ) = √450 = 15√2 cm
