Is a pentagonal pyramid a hexahedron or pentahedron?
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 apexIt 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.
What are examples of nested solids?
three examples of nested solids
The number of Platonic solids?
There are 5 platonic solids. They are: Tetrahedron, Octahedron, Icosahedron, Cube, and Dodecahedron
Why are there only five platonic solids?
Because 6 platonic solids would be too many, and 4 wouldn't be enough
What solids have 6 faces?
cubes
How many Johnson solids were named and described by the mathematicians Norman Johnson?
92
Who first discovered the platonic solids?
Theaetetus, a Greek mathematician.

Who are the platonic solids named after?
they are named after plato, an ancient greek philosopher, who described them in one of his books
What property must a solid have to be a crystalline solid?
The specific property that distinguishes crystalline solids from other types of solids (other types would be described as amorphous solids) is that their constituent atoms are arranged in orderly geometrical patterns.

Who invented density bottle?
The density bottle was invented by the Irish scientist and mathematician Lord Kelvin, also known as William Thomson, in the 19th century. He developed this apparatus to accurately measure the density of liquids and solids by weighing them.
What has the author Clarence Everet Johnson written?
Clarence Everet Johnson has written: 'Adjustment of the ratio of fat to nonfat solids by means of nonfat dry milk in the manufacture of cheddar cheese from high fat content milk' -- subject(s): Cheddar cheese
What is diffrance between amorphous solids and crystalized solids?
Crystalline solids have a particular geometric organization of their atoms. Amorphous solids do not.
Are solutions all solids?
Not all solutes are solids.
