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.
6 vertices, 2 triangular faces, 3 rectangular sides, 9 edges
