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.

Just that, a pentagonal based pyramid.

pentagonal pyramid

a pentagonal pyramid or a pentagonal prisim

Five (and a pentagonal base).Five (and a pentagonal base).Five (and a pentagonal base).Five (and a pentagonal base).

It depends on what type of pyramid. Their is an square pyramid, a rectangular pyramid, a pentagonal pyramid, etc.

a pentagonal pyramid is also known as a pentahedron

A pentagonal pyramid is a hexahedron with a pentagonal face.

Yes, it is.

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 is to hexagon as pentahedron is to pentagon.

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

The generic term is a hexahedron. It can be a pentagonal pyramid, or a quadrilateral prism (or a more irregular version of that).

i think it's ... pentagonal pyramid. hope this helps you. :)

pentagonal pentahedron.

A six sided polyhedron is a hexahedron. This may be a triangle based dipyramid, a pentagonal pyramid of a variant of a parallelepiped.

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.
