triangular prism
i don't if thats right somewhere else, but if you're from connexus its rectangular prism.
Improved answer:
I sense confusion between the question and the reply. A triangular prism has six vertices. An infinite amount of solid objects have more vertices. The question "Which solid figure has the least vertices" is probably the intended question, in which case the answer is a tetrahedron or spheroids. The tetrahedron has four vertices, the least number a solid with only planar surfaces can have. Of course any number of solids have no vertices, like the sphere and other spheroids.

There is no limit to the number of vertices that a solid figure can have.

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...
It has 8 vertices.

A solid figure with eight vertices and all faces of equal size is called a cube. Each face of a cube is a square, and a cube has 8 vertices and 6 faces.
