A 120-sided polyhedron is a hecatonicosahedron.
A polyhedron that has 2 congruent faces is a PRISM. To be a prism, all the other sides (not including the 2 that are congruent) have to be 4-sided.
A 14-sided and 3-dimensional shape is called either a tetrakaidecahedron or tetradecahedron. This 14-sided polyhedron can have six quadrilateral and eight hexagonal faces.
That depends on what the shape of the faces of each side of the polyhedron is - since a ten-sided figure does not create a regular polyhedron, it is impossible to calculate its volume based simply on this information.
no a cuboid is not a polyhedron if it was it would have 9 faces
A polyhedron with 20 faces is called an icosahedron.
An octahedron, which looks like 2 pyramids glued bottom to bottom.
A one-hundred sided polyhedron is called a hecatohedron, comming from the Greek Hecto- meaning one-hundred and -hedronmeaning a three-dimensional figure.
A 20-sided polyhedron is called an icosahedron. It has 20 equilateral triangle faces, 30 edges, and 12 vertices. It is a regular convex polyhedron with rotational symmetry.
Octohedron
I believe it called a Bucky Ball. After Buckminster Fuller.
Oh, dude, you're looking for a pentagon. It's like a shape with five sides in 2D, but when you add some depth to it, it becomes a pentagonal prism. So, yeah, pentagon is the name you're after.
a polyhedron (if the shape is 3 dimensional) a polygon if it is a planar shape.
A 120-sided polyhedron is a hecatonicosahedron.
A shape in 2D with n sides is called an n-gon. In higher dimensions, a shape with n sides is called an n-sided polyhedron.
A 2D seven sided figure is called a heptagon. A 3D seven faced polygon is called a heptahedron.
In geometry, a hendecagon (also undecagon or endecagon) or 11-gon is an eleven-sided polygon.
