A block for interior and exterior materials of a building is provided to produce various cubic effects by forming the outward appearance of a finishing material in a pentahedral block and attaching to the surface of a wall to make one side of the pentahedral block to be arranged in various shapes. A block for interior and exterior materials of a building, as a finishing material for finishing an internal wall or an external wall of a building, is formed in a pentahedral block having one a regular tetragon(Q), two right-angled isosceles triangles(T1) and two right-angled triangles(T2) by cutting into three equal parts from two vertexes located in the diagonal direction of a regular hexahedron, and gives cubic effects by attaching the pentahedral blocks to an internal wall and an external wall of a building to be arranged in various shapes to be projected in the specific shape from the surface of the walls.
