Square pyramid.
The figure is a square pyramid. It is made with a square on the bottom and 4 triangles meeting at a vertex perpindicular to the square. The square has 1 face, the 4 triangles each have one face making 5 faces. The edges are made where the triangles meet each other and where they each meet the square. There are four vertices at the corners of the square and the one at the top of the pyramid.
A pyramid with a square base.

3 squares and 4 triangles will have 24 vertices. There will be 4 vertices for each of the 3 squares. Since there are 3 squares, that will be 12 vertices. There are 3 vertices for each of the 4 triangles. Since there are 4 triangles, that will be 12 vertices. 12+12=24.
A hexagon has more vertices.
The rectangular pyramid - it has a square base, so has four vertices rather than the three of a triangular one.

A pyramid is a three-dimensional figure with five verticies and five sides (four of which are triangles and one of which is a square). A pentagon is a two-dimensional figure with five angles and five edges.
