The cube have: -- six (6) faces -- twelve (12) edges -- zero (0) curved surfaces -- eight (8) vertices
0 edges 0 faces (faces are planar bounded by linear edges) 2 curved surfaces 1 vertex
The description given fits that of cones
There are two plane faces and a curved face, two edges and no vertices.
6 flat surfaces - known as faces, 12 edges 8 vertices.

A cylinder has 2 surfaces (faces), 0 vertices, and 0 edges.
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices.
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.
Faces-2 (1 flat face and 1 curved face), 1 curved edge, and 1 vertex.
6 flat surfaces - known as faces, 12 edges 8 vertices.
The three parts are faces, vertices and edges. The faces are the flat surfaces, the edges are the lines that joint the corners which are called vertices.
A cylinder has three faces and two round surfaces.
A hemisphere as two faces (one curved and one plane), one edge and no vertices.
