Where did the name octahedron come from?
A polyhedron is closed a 3-dimensional figure whose faces are all polygons. The prefix "octa-" refers to eight and an octahedron is a polyhedron with 8 faces.
What is the relationship with octahedron and icosahedron?
They are both 3 dimensional shapes with faces that are polygons.
Which 3-dimensional figure has no faces?
a sphere
Is a cube a square?
No. A square is a 2-dimensional figure. A cube is a 3-dimensional figure whose faces are all squares.
Is a heptagon 3 D?
No. Like all polygons, a heptagon is a 2-dimensional closed figure.

What is required for a polyhedron?
It is a 3-dimensional shape whose faces are all polygons.
What is the relationship with octahedron and icosahedron?
They are both 3 dimensional shapes with faces that are polygons.
What do you call a 3 dimensional shape with 16 faces?
A 3 dimensional figure
Which 3-dimensional figure has no faces?
a sphere
How many faces vertices and edges does a rectangle have?
Rectangles are plane (2-dimensional) polygons. Only solid (3-dimensional) polyhedrons have faces.
How is a shape a polyhedron?
A polyhedron is a 3-dimensional shape whose faces are all polygons.
What 3D figure have polygons for bases?
Many 3-d figures can have polygons for bases. If all ist faces are polygons then it is a polyhedron but it is possible to have 3-d figures with a polygonal base and non-polygonal faces.
What 3 dimensional figure has 2 faces?
That would be a cylinder, with the faces on each end.
Which 3-dimensional figure has onely squre faces?
A cube has onely square faces.
Are three-dimensional shapes with faces consisting of polygons Answer?
No. A sphere is a three dimensional shape which has no polygonal faces. Similarly an ellipsoid, a torus, a paraboloid, hyperboloid etc are 3-D shapes with no polygonal faces.
What two-dimensional geometric figure does not have 3 vertices and 3 sides?
All of the polygons except the triangle
