A pentagonal heptahedron is a heptahedron comprising two pentagons which are joined to one another by five quadrilaterals. There is no requirement for the pentagons to be congruent nor for them to be parallel to one another.
A hexagonal based pyramid is the best description since it is not ambiguous. The shape is a heptahedron but that name could also apply to a pentagonal prism as well as some exotic shapes.
A polyhedron of 5 or more sides can always be found that has a rectangular face. So three shapes are:a pentahedron (rectangle based pyramid),a hexahedron (cuboid),a heptahedron (pentagonal pyramid).

A pentagonal what? A pentagonal pyramid or pentagonal prism have different numbers of vertices.
A pentagonal heptahedron. A heptahedron is a solid figure with seven faces, and a pentagon is a five-sided plane figure.
A heptahedron is a closed 3-d shape with 7 polygonal faces. There are 34 topologically different convex heptahedra and, since none of these are regular, the term is ambiguous. Some of these, such as the hexagonal pyramid, or [a right] pentagonal prism have names but even the latter is a special case of a pentagonal prismoid. There are many names for heptahedra.
A heptahedron. It could be a pyramid with a hexagonal base, or a pentagonal prism. There are other possibilities but no obvious names spring to mind.

A heptahedron can have 6 to 10 vertices.
A heptahedron is a closed 3-d shape with 7 polygonal faces. There are 34 topologically different convex heptahedra and, since none of these are regular, the term is ambiguous. Only the right pentagonal prism, a very special version of one of the 34 topological forms has 5 faces which are perprdicular to the other 2.
A heptahedron has seven faces, like a heptagon has seven sides.
Can ypu please help with my sons homework question which is - Name two 3-D shapes that have 7 faces I think it is called a heptahedron, but check to be sure. * * * * * A heptahedron is a generic name for any solid with seven polygonal faces. If its is you son's homework, it is likely they are looking for more specific examples. Here are two: A pentagonal prism and a hexagonal pyramid.
A heptahedron is a polyhedron with seven faces. The number of vertices in a heptahedron can be determined using Euler's formula, which states that for any polyhedron, the number of vertices (V), edges (E), and faces (F) are related by the equation V - E + F = 2. Since a heptahedron has 7 faces, the equation becomes V - E + 7 = 2. The number of edges in a heptahedron can vary depending on its specific shape, so the number of vertices cannot be determined without additional information about the edges.
A heptahedron has 7 faces, including 6 triangular faces and one hexagonal.
A polyhedron of 5 or more sides can always be found that has a rectangular face. So three shapes are:a pentahedron (rectangle based pyramid),a hexahedron (cuboid),a heptahedron (pentagonal pyramid).
