How many faces does a 10 sided Decagonal pyramid have?
How many faces does a 10 sided Decagonal pyramid have?
The decagonal prism has 12 faces, 30 edges, and 20 vertices, so, it is a dodecahedron (while the term is usually applied to regular dodecahedron or rhombic dodecahedron.).

Do pyramids have 8 sides?
Despite what you may think about this ancient structure, the Great Pyramid is an eight-sided figure, not a four-sided figure. Each of the pyramid’s four side are evenly split from base to tip by very subtle concave indentations. It is believed that this discovery was made in 1940 by a British Air Force pilot named P.

What is a 3D shape with 7 sides called?
A heptahedron is a polyhedron with seven faces.
What is the smallest 3D shape?
tetrahedron
In geometry, a polyhedron is a solid in three dimensions with flat faces and straight edges. Every edge has exactly two faces, and every vertex is surrounded by alternating faces and edges. The smallest polyhedron is the tetrahedron with 4 triangular faces, 6 edges, and 4 vertices.
