anything that has more than nine sides is called the number of faces, in this case 20, with agon added to it. so a figure with twenty faces or sides is called a twentyagon.
A geometric figure with a polygonal base and triangular sides is called a pyramid.
The regular solid, with 20 identical equilateral triangular faces, is called an icosahedron.
A rectangular prism.
a geometric figure having a specified kind or number of faces.
A figure with six equal faces is called a cube. Each face of a cube is a square, and all its edges and angles are equal. This three-dimensional shape is a fundamental geometric figure often found in various contexts, including architecture and design.
A solid figure with twenty faces is called an Icosahedron.
A geometric figure with a polygonal base and triangular sides is called a pyramid.
The regular solid, with 20 identical equilateral triangular faces, is called an icosahedron.
A rectangular prism.
Not any geometric figure.
Such at figure - as described - could not be made as a solid geometric shape.
A tetrahedron.
a geometric figure having a specified kind or number of faces.
A rectangular prism, pentagonal pyramid
