A triangular prism - if the three rectangular face are not ALL the faces.
Any solid object with six faces is a hexahedron. A regular hexahedron (with 12 edges) is a cube where all the faces are squares An irregular hexahedron (with 12 edges) is a cuboid where two faces are equal squares and four are equal rectangles.
A solid with six congruent square faces is a cube.
A cube has six square faces.
A rectangular prism has six faces, eight vertices, and twelve edges. All of the faces are either rectangles or squares.

A cube is a three dimensional figure with all edges having the same length and all six sideshaving the same area. The length of a cube is the length of any edge of the cube; all edges having thesame length.
A tetrahedron is a solid figure with 6 edges. There's no such thing as solid edges. A tetrahedron is a triangular pyramid, with 4 vertices, 6 edges and 4 triangular faces. In a regular tetrahedron (the first Platonic solid) all triangles are equilateral.
