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.

What is a hexagonal based pyramid called?
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.
What are three different geometric solids that have at least one rectangular face?
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).
How many vertices are in a pentagonal?
A pentagonal what? A pentagonal pyramid or pentagonal prism have different numbers of vertices.
What is the name of a shape with 7 faces?
heptahedron
How many faces dose a heptahedron have?
999,999,000
What shape has 7 faces 5 being perpendicular to the other 2?
A pentagonal heptahedron. A heptahedron is a solid figure with seven faces, and a pentagon is a five-sided plane figure.
What is a heptahedron figure known as?
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.
What is a solid figure with 7 plane faces called?
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.
What polyhedron has more faces that a hexahedron by fewer faces that an dodecahedron?
A heptahedron is one possible answer.A heptahedron is one possible answer.A heptahedron is one possible answer.A heptahedron is one possible answer.
What is a hexagonal based pyramid called?
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.
How many vertice does heptahedron have?
A heptahedron can have 6 to 10 vertices.
Does a heptahedron have 5 faces perpendiculer to the other 2?
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.
How many faces does a heptahedron have?
A heptahedron has seven faces, like a heptagon has seven sides.
What 3 d shape has 7 faces?
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.
How many corners does a heptahedron have?
A heptahedron has 7 faces, including 6 triangular faces and one hexagonal.
How many vertices does a heptahedron have?
There is no simple answer to this question. Polyhedra are named according to the number of faces that they have. A heptahedron is a 3-dimensional shape with 7 faces. It could be in the form of a pyramid with a hexagonal base. In that case, it has 7 vertices. Or it could be in the form of a prism with pentagonal bases and in that case it has 10 vertices. There are many different configurations, and the number of vertices varies. As stated in the answer by Ngc0202, there can be anything from 6 to 10 vertices.
What are three different geometric solids that have at least one rectangular face?
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).
