A parallelepiped has a square base area of 90 and volume 660. Find the total area of the parallelepiped, the face diagonal and the diagonal of the parallelepiped.
Hmm, is that a cube? If not, what? how do i solve? Thanks
It certainly won't be a cube (where all the faces are squares), but it might be a cuboid (where some faces are rectangles). But unless you're told this, there's no way that you can calculate the area of the faces. So we need more information, I'm afraid.
