The cube have: -- six (6) faces -- twelve (12) edges -- zero (0) curved surfaces -- eight (8) vertices
There are two plane faces and a curved face, two edges and no vertices.
A hemisphere as two faces (one curved and one plane), one edge and no vertices.
A sphere has no edges or edges but its face is globular.
0 edges 0 faces (faces are planar bounded by linear edges) 2 curved surfaces 1 vertex
A cube or a cuboid both would fit the given description both of which have 8 vertices, 12 edges and 6 faces.

Euler's definition do not apply to curved solids. faces must be polygons; they cannot be circles. using the conventional definitions of faces, edges and vertices, This question causes frustration for teachers and students. Euler's definitions of edges, faces and vertices only apply to polyhedra. Faces must be polygons, meaning comprised of all straight sides, edges must be straight, and vertices must arise from the meeting of straight edges. As such, a cylinder has no faces, no edges and no vertices, using the definitions as they apply to polyhedra. You need to create a different set of definitions and understandings to apply to solids with curved surfaces.
