    Hi bluffmaster.roy.007,

    V_A=1728

    V_B=13824

    Each edge of the cube A is 12 m
    Each edge of the cube B is 24 m

    SA of cube A is 6(144).

    SA of cube B is 6(576).

    \frac{SA_A}{SA_B}=\frac{6(144)}{6(576)}=\frac{1}{4  }

    If this is a quantitative comparison question, then the quantity in col B is greater.
