    Answer :

    81 cm²

    Solution :

    • Given : Volume = 729 cm³
    • To find : Base Area = ?

    Here ,

    It is given that the volume of the cube is 729 cm³ .

    Thus ,

    => Volume = 729

    { Volume of cube = Side³ }

    => Side³ = 729

    => Side³ = 9³

    => Side = 9

    Now ,

    The Base Area the cube will be given as ;

    => Base Area = Side²

    => Base Area = 9²

    => Bade Area = 81 cm²

    Hence ,

    Area of the base of the given cube is 81 cm² .
