Respuesta :

This is a triangular pyramid and has 4 faces.

Answer:

5

Step-by-step explanation:

Faces is essentially the number of sides. In an easier shape like this you could just count the number of sides. You would have 5 faces in this shape.

On a side note, when dealing with convex polyhedrons(you might not have gotten into this) you can find the number of edges by by adding the number of vertices, plus the number of vertices, minus 2.

For example, lets take a cube. The cube has 6 faces and 8 vertices. 6 + 8 - 2 = 12 edges
