    Question

    The volume of a cube is 1728 cm³. Find its total surface area (in cm²).

    A.

    884

    B.

    764

    C.

    864

    D.

    784

    Correct option is C

    Given:

    Volume of cube V = 1728 cm3728\ \text{cm}^3​​

    Formula Used:

    For a cube with side (a): V = a3a^3​​

    Total Surface Area (TSA) = 6a26a^2​​

    Solution:
    a3=1728a^3 = 1728

    a=17283=12 cm = \sqrt[3]{1728} = 12\ \text{cm}​​

    TSA=6a2=6×122=6×144=864 cm2\text{TSA} = 6a^2 = 6 \times 12^2 = 6 \times 144 = 864\ \text{cm}^2​​
