What is the name of a shape with 2 hexagon faces and 8 square faces?
hexagonal prism
What shape has 8 faces 12 vertices and 18 edges?
the shape that has 8 faces , 18 edges , and 12 vertices is simply a hexagonal prism not a pyramid my butt :P
How many faces does a pentagonal shape have?
A pentagonal shape has 5 faces. For determining the name of a shape, it is determined by the amount of faces. For determining the amount of faces on a shape, it is determined by the pre fix of a word. tri-3 quad-4 pent-5. hex-6 hept-7 oct-8 non-9 deca-10 and so on.
Name a 3D shape with 7 faces of which 5 are rectangles and the other 2 are pentagons?
Pentagonal prism.
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 is the name of a 3d shape with 8 faces?
Octagon. * * * * * An octagon is 2-dimensional. The regular 3-d shape (all faces the same) is the octahedron, but a hexagonal prism also has 8 faces.
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.
Name the faces of the 7 sided polyhedron?
There are a number of possible 7-sided polyhedra. Three that come immediately to mind are: a hexagonal pyramid, a pentagonal prism, a "stretched" triangular pyramid (triangular base, rectangular sides, and then triangular faces meeting at an apex).
What is the name for a 3D with 7 vertices's?
A hexagonal pyramid is one possibility. A pentagonal bi-pyramid is another. There are others.
How do you figure out the edges in a 3D shape?
There is no simple way. You cannot go by the name - which can refer to the number of faces. You can have different shapes with the same number of faces. The following are all examples of a hexahedron (six faces): triangular dipyramid (9 edges), pentagonal prism (10 edges), rectangular prism (12 edges). One contributor has suggested it might be easier to count the faces and vertices (corners). Add the two numbers and then subtract 2. *This will work if the shape has been simplified as much as it can be. The 2 is only valid if there are no holes in the shape. For example, a pentagonal prism: 6 faces, 6 vertices. Sum = 12. Subtract 2 = 10. A pentagonal pyramid has 10 edges.
Name of a 3D shape with 8 sides?
hexagonal prism In geometry, the hexagonal prism is a prism with hexagonal base. This polyhedron has 8 faces, 18 edges, and 12 vertices. Since it has 8 faces, it is an octahedron. However, the term octahedron is primarily used to refer to the regular octahedron, which has eight triangular faces. https://en.wikipedia.org/wiki/Hexagonal_prism#/media/File:Hexagonal_prism.png
What is the name of a ten sided 3d shape?
Pentagonal trapezohedron.
