    A 8 cm Correct Answer Incorrect Answer
    B 6 cm Correct Answer Incorrect Answer
    C 9 cm Correct Answer Incorrect Answer
    D 5 cm Correct Answer Incorrect Answer

    Solution

    Ratio of length, width, and height =2:2:3 Let length =2x, width =2x, height =3x. Volume of cuboid =l×b×h 3x ×2x×2x =768 12x3 =768 x3 =64 x = 4cm now the length of the cuboid =2×4 =8cm.
