3d shapes with six faces are called hexahedra.
polyhedra
A tetrahedron is a polyhedron with four triangular faces, while a triangular prism is a polyhedron with two triangular faces and three rectangular faces. The main difference between the two shapes is their number of faces and their base shapes. Additionally, a tetrahedron has four vertices and six edges, while a triangular prism has six vertices and nine edges.
There are multiple shapes that meet this condition. The most obvious one being the cube, with six square faces of equal size. Another one would be a rhombohedron, which would be like a sheared cube. It has six equal faces, but they are rhombuses.
Many solid shapes could have 6 faces, but the most common such shape, with 6 equal faces, is the cube.

3d shapes with six faces are called hexahedra.
A cube has only one shape and that is of a cube! It has six faces.
Six more.

polyhedra
A cube has eight vertices and six faces (think of a die!).
It is a solid shape with six faces. There are seven topologically distinct convex shapes and three concave ones. The faces can be triangles, quadrilaterals or pentagonal and the number of edges can range from 9 to 12. The number of vertices is 4 fewer than the number of edges.
A regular hexahedron (a.k.a.: a "cube") has six squarefaces.However "hexahedron" simply means "six faces", so a non-regular hexahedron could have faces of other shapes. For example:A triangular dipyramid has six triangular faces.A parallelepiped has six parallelogram faces.A triangular trapezohedron has six kite-shaped faces.A pentagonal pyramid has a pentagonal base, and five triangular sides.
