In geometry, a pentagonal pyramid is a pyramid with a pentagonal base upon which are erected five triangular faces that meet at a point (the vertex). Like any pyramid, it is self-dual.
The regular pentagonal pyramid has a base that is a regular pentagon and lateral faces that are equilateral triangles. It is one of the Johnson solids (J2). Its height H, from the midpoint of the pentagonal face to the apex
It can be seen as the "lid" of an icosahedron; the rest of the icosahedron forms a gyroelongated pentagonal pyramid, J11. The 92 Johnson solids were named and described by Norman Johnson in 1966.
More generally an order-2 vertex-uniform pentagonal pyramid can be defined with a regular pentagonal base and 5 isosceles triangle sides of any height.

A pentagonal pyramid is also known as a pentahedron.
Does a hexahedron have pentagon faces?
A pentagonal pyramid is a hexahedron with a pentagonal face.
Is a pentagonal pyramid a hexahedron?
Yes, it is.
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).

hexahedron ex:cube, triangular dipyramid, triangular deltohedron, pentagonal pyramid

a regular hexahedron. other types of hexahedron include: • cuboid • parallelepiped • pentagonal pyramid • quadrilateral frustum • rhombohedron • triangular dipyramid • trigonal trapezohedron
What is a space figure with 6 faces?
The generic term is a hexahedron. It can be a pentagonal pyramid, or a quadrilateral prism (or a more irregular version of that).
What 3d shape has 5 triangular faces and 1 pentagonal face?
i think it's ... pentagonal pyramid. hope this helps you. :)
What solid shape has five faces?
pentagonal pentahedron.
What is the name of a six sided polyhedra?
A six sided polyhedron is a hexahedron. This may be a triangle based dipyramid, a pentagonal pyramid of a variant of a parallelepiped.
What is the formula for calculating the volume of a hexa?
There is no shape called a hexa so the question makes no sense.If the question was refering to a hexahedron, there is insufficient information since a hexahedron can be a triangular dipyramid, a pentagonal pyramid or a quadrilateral prism or rhombohedron or a number of related shapes. Each one of these has a different formula.There is no shape called a hexa so the question makes no sense.If the question was refering to a hexahedron, there is insufficient information since a hexahedron can be a triangular dipyramid, a pentagonal pyramid or a quadrilateral prism or rhombohedron or a number of related shapes.
