The volume of a cube is 729 cubic inches. what is the area of the cube face

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.
