Investigate a "dodecahedron"
A 12 sided 3D shape is called a dodecahedron.
10 sided shape: Decagon
The equation for and interior angle of an n sided shape is (n-2)180/n In this case we have a 12 sided shape. Plugging n=12 into the equation gives us: (12-2)180/12 = 10x180/12 = 150 Thus an interior angle of a 12 sided shape would be 150 degrees.
A shape with 12 sides is known as a Dodecagon.
A 12 sided shape is called a dodecagon.
a 4 sided 3d shape is called a triangular prism!!!!!!!!!!!!!!!
a 12 sided shape.
A 12-sided shape is called a dodecagon.
A 12 sided 3D shape is a dodecahedron.
Shapes with 12 to 20 sides are named as follows: a 12-sided shape is called a dodecagon, a 13-sided shape is a triskaidecagon, a 14-sided shape is a tetradecagon, a 15-sided shape is a pentadecagon, a 16-sided shape is a hexadecagon, a 17-sided shape is a heptadecagon, an 18-sided shape is an octadecagon, a 19-sided shape is a nonadecagon, and a 20-sided shape is an icosagon.
12-sided two dimensional shape: dodecagon12-sided three dimensional shape: dodecahedron
A cuboid or rectangular prism.
Hexagonal prism
A 12 sided 3D shape is called a dodecahedron.
A ten-sided prism, also known as a decagonal prism, is a three-dimensional geometric shape with two parallel, congruent decagonal (10-sided) bases connected by rectangular lateral faces. The lateral faces are perpendicular to the bases, and there are a total of 12 faces, 20 edges, and 30 vertices in a decagonal prism. This shape is a type of polyhedron and is part of the broader category of prisms, which are defined by having two identical bases connected by rectangular sides.
There are many possibilities, and here are a couple: A dodecagonal prism (dodecagon = 12 sided plane figure); A heptagonal pyramid (heptagon = 7 sided plane figure).
The bases are pentagons - 5 sided polygons.
