    Answer:

    Step-by-step explanation:

    Formula of Volume= a^{3} – a = side

    Therefore since the volume is given you just need to find the side.

    729=a^{3} = \sqrt[3]{729} = a

                = 9 = a

    Now you know that 9 is the side, so using that find the area of one face-

    Area of a square= 9 x 9 = 81cm^{2}
