A square-based pyramid.
A 3d shape can have infinite sides
A right square based pyramid.
sides are the face of a 3d shape and verticies are the corner of the shape
A pentagonal pyramid.
A septadecahedron has 17 sides to it.
A 3d shape can have infinite sides
5 sides.
A right square based pyramid.
If it's 3D then it could be a rectangular pyramid.
sides are the face of a 3d shape and verticies are the corner of the shape
square
That is a Dodecahedron.
A pentagonal pyramid.
A septadecahedron has 17 sides to it.
Pentadecagon; Pentakaidecagon
I would say a square-based pyramid but there are many 3 dimensional shapes with 5 sides.* * * * *The generic name is a pentahedron.
2D shape = Decagon 3D shape = Decahedron
