    Volume of a cube=side³ ⇒side=∛ (volume of a cube)

    side=∛ (729 in³) = 9 in

    area of the cube face=side² = (9 in) ²=81 in²

    The cube have 6 faces; therefore:

    area of the cube faces=6 (81 in²) = 486 in²

    Answer: the area of a face of this cube will be 81 in², and the area of the cube faces would be 486 in².
