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 else can I help you with?
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 the bases of the heptahedron?
The bases of a heptahedron are the two parallel polygonal faces that form the top and bottom of the solid shape. These bases are connected by lateral faces, which are also polygons, to form a three-dimensional figure with seven faces, known as a heptahedron.
What is a 7 sided 3d shape is called?
A 2D seven sided figure is called a heptagon. A 3D seven faced polygon is called a heptahedron.

How many vertice does heptahedron have?
A heptahedron can have 6 to 10 vertices.
How many plane sides does a heptahedron which is a solid figure have?
"Hepta" means "seven", just like "hexa" means "six" etc...
How many faces does a heptahedron have?
A heptahedron has seven faces, like a heptagon has seven sides.
What is a pentagonal heptahedron?
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.
How many corners does a heptahedron have?
A heptahedron has 7 faces, including 6 triangular faces and one hexagonal.
How many pairs of parallel faces are in a heptahedron?
A heptahedron is a seven-faced polyhedron. The number of pairs of parallel faces in a heptahedron can vary depending on its specific shape and configuration. For example, a regular heptahedron, such as a truncated triangular prism, may have pairs of parallel faces, while other irregular heptahedra may not have any. Therefore, the answer is not fixed and can range from zero to multiple pairs based on the specific heptahedron in question.
How many edges does a heptahedron have?
7
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.
