Assuming that demination is meant to be dimension, the answer is a triangular prism.
Not any geometric figure.
A tetrahedron.
A pyramid with a square base.
A cube
A cuboid is a geometric solid figure that has six rectangular faces at right angles to each other. It has 12 edges and 8 vertices.
It is a TETRAHEDRON . Incorrectly named a triagular pyramid.
Square pyramid.
If you are a solid figure with no vertices or edges, then you are a Sphere.From the lighter side: And that means that we can no longer be friends...
A shape with 5 vertices and 8 edges is known as a triangular prism. This three-dimensional geometric figure has two triangular bases and three rectangular lateral faces. It consists of 5 vertices (3 from one triangle and 2 from the other) and 8 edges (3 from each triangle and 3 connecting the vertices of the triangles).
