Advertisement Advertisement evab evab Answer: 12 sides. I hope this is the right. Advertisement Advertisement New questions in Math. Euclid's fifth postulate By subtracting 20 on both the sides, we can write, F = 32 – 20 = 12 So, there are 12 faces given to the dodecahedron. Therefore, option (a) is the right answer. Note: Be careful with the formula because there are many variables students substitute one value in place of the other.

A regular dodecahedron has 20 vertices, 12 faces and 30 edges. A dodecahedron can also be a endacagon based pyramid which has 12 vertices, 12 faces and 22 edges, or A decagon based prism which has 20 vertices, 12 faces and 30 edges, or one of many other configurations Best Answer. Copy. A dodecahedron is a generic term which describes a 3-dimensional shape with 12 polygonal faces. There are approx million topologically different convex dodecahedra plus concave ones.
How many faces edges and vertices does a dodecahedron have?
How many sides would a regular polygon have if one of its exterior angles measures 30 degrees? If one of its exterior angles is 30 degrees, then it is a star with 6 points and 12 sides. degrees / 30 degrees = 12 angles It is a regular dodecahedron. Related questions 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 How many diagonals does a shape with 8 sides have? The formula for determining the number of diagonals in a shape is n(n-3)/2 where n=vertices, (corners or intersections of geometric shapes). For an eight sided shape we replace n with 8. 8()/2 8(5)/2 (8x5)/2 40/2=20 An octagon contains 20 diagonals 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 How many faces does a dodecahedron?
