Question

6 faces that are rectangle 8 vertices 12 edges?

Answer 1

In the case of a cuboid this gives 6 + 8 = 12 + 2; that is, like a cube, a cuboidhas 6 faces, 8 vertices, and 12 edges. Along with the rectangular cuboids, any parallelepiped is a cuboid of this type, as is a square frustum (the shapeformed by truncation of the apex of asquare pyramid).
