    Step-by-step explanation:

    let the edge of cube =acm

    Volume =a^ 3

    a^3 =729

    a^3 =9^3

    a = 9 cm

    lateral surface area=4×9^2

    =324cm^2

    Total surface area =6a^2=

    = 6×81=486cm^2

    Answer:

    468 cm^2

    Step-by-step explanation:

    let side of the cube be a cm then,

    volume of cube = a^3

    a^3 = 729

    a = 9 cm

    now surface area of cube = 6a^2

    SA = 6.9^2 = 6.81

    SA = 486 cm^2
