A quadrilateral bipyramid is one possible answer. This is two pyramids with the same quadrilateral base - one on each side of the "base".
This is an Octahedron!
Its a Octagon * * * * * No. An octagon is a shape with 8 sides. 8 faces implies a 3-dimensional object, which would have to be an octahedron.
the 3 dimensional shape is a octagon, because their are 8 sides.
Octohedron
A cube.
A shape with 8 faces is called an octahedron. An octahedron is a polyhedron with eight faces, each of which is an equilateral triangle. It is a three-dimensional shape that is commonly used in geometry and mathematics.
That's impossible. A shape has three or more sides/faces. There is NO shape that has one or two sides/faces
An octagon has 8 faces. In geometry, a face refers to a flat surface on a 3D shape. An octagon is an 8-sided polygon with 8 straight sides and 8 angles. Each side of the octagon forms a face, resulting in a total of 8 faces.
A quadrilateral based pyramid.
Your shape is a triangular octagon. * * * * * What on earth is that shape? The most likely answer is an octogonal pyramid.
Shapes have sides. Do you mean, what shape has 6 sides or, what solid has 6 faces?
A shape's sides are called faces.
