Given: \(Q\) is a cube, so all sides are equal.

From statement 1, we know the surface area so the length of a side can be calculated. So, sufficient \(\Large{\color{green}\checkmark}\)

From statement 2, we know the diagonal length, so again we can calculate the side length and gets the volume of the cube. So, sufficient \(\Large{\color{green}\checkmark}\)
