A regular dodecahedron has 12 pentagonal faces. • It has 12 pentagonal faces. Each face has 5 sides of equal length. • It has 30 vertices and 60 edges. • It is a polyhedron, specifically an isohedra (one of the five Platonic solids). • It is named "dodecahedron" because it has 12 faces (dodeca = 12). • It has 5-fold rotational The regular dodecahedron is a Platonic solid. Edge length and radius have the same unit (e.g. meter), the area has this unit squared (e.g. square meter), the volume has this unit to the power of three (e.g. cubic meter). A/V has this unit Net of a dodecahedron, the three-dimensional body is unfolded in two dimensions How many sides does a dodecahedron have? How many sides does an octahedron have? 8. How many sides does a cube have? 6. How many sides does an How many sides does each face of a dodecahedron have? 12 sides Dodecahedron is derived from the Greek word “dōdeka” means “12” and “hédra” means “face or seat” that shows that it is a polyhedron with 12 sides or 12 faces. Hence, any polyhedra with 12 sides can be called a dodecahedron. It is made up of 12 pentagonal faces How many sides does a dodecahedron have? See answer Advertisement Advertisement hgyeong hgyeong Answer: mark me as Brianlist. Explanation: A regular dodecahedron or pentagonal dodecahedron is a dodecahedron that is regular, which is composed of 12 regular pentagonal faces, three meeting at each vertex. It is one of the It has 20 faces. The number of edges will depend on the exact configuration of the shape. For example, a icosahedron in the form of a prism, with gons as bases, will have 54 edges. On the other hand a pyramid with a gon base will have 38 edges. A bipyramid with a decagon base will have 30 edges. There are very many more possible A dodecahedron with sidelength a a has 60 60 surface diagonals and space diagonals, 10 10 being long, 30 30 being medium, and 60 60 being short. I have figured out length of long diagonal is a 1 +ϕ4− −−−−√ a 1 + ϕ 4 and medium diagonal is aϕ2 a ϕ 2 but I couldn't find the short diagonal. geometry. solid-geometry The dodecahedron and icosahedron are dual polyhedra. A regular dodecahedron has 12 faces and 20 vertices, whereas a regular icosahedron has 20 faces and 12 vertices. Both have 30 edges. When a regular dodecahedron is inscribed in a sphere, it occupies more of the sphere's volume (%) than an icosahedron inscribed in the same sphere (%)

Several special types of dodecagons are illustrated above. In particular, a dodecagon with vertices equally spaced around a circle and with all sides the same length is a regular polygon known as a regular dodecagon. How many faces does a dodecahedron have? The dodecahedron has 30 edges, 20 vertices and 12 faces 8 more. A dodecagon has 12 sides. A quadrilateral has 4 sides. A dodecagon is a polygon with exactly 12 sides.A dodecagon has 12 sides A dodecahedron always has a total of twelve sides. In a regular dodecahedron, each side is shaped like a pentagon.

How many vertices does a dodecahedron pyramid have? A dodecahedron pyramid does not [HOST]r, a dodecagon pyramid exists. If a dodecagon has 12 sides, there would be 12 vertices. But all the vertices would join up to make a vertex, making one extra vertex. 12 + 1 = 13 Lesson Summary. Frequently Asked Questions. What 3D shape has 12 sides? Any 3-D shape that has twelve sides is called a dodecahedron. Whether it is
