Q:
# How many vertices does a triangular pyramid have?

**A triangular pyramid has four vertices and six edges.** It is comprised of four equilateral triangles, with any one triangle being used as the base and the others connecting at the vertices to form a pyramid.

The geometric word for this type of pyramid is "tetrahedron." To calculate the volume of a tetrahedron, one should first find the base triangle's area by multiplying the base by the height and dividing that number by 2. Then, that figure is multiplied by the height of the pyramid and multiplied again by 1/3. To calculate the surface area of the pyramid, the same formula is used as in figuring the base area. That figure is multiplied by 4 since the pyramid has four triangle faces.
