5 faces
Eight.
There are 5 edge (also known as vertices) on a square-based pyramid. 4 on the base and the last edge on the top of the pyramid.
A triangular prism has a triangular base. A square-based prism has a square base. A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges.
Eight edges (four edges on the square bottom, and one edge going from the vertex to each of the four corners of the square).
The perimeter of a square is 100 inches. How many square tiles 1 inch on each edge are needed to cover its area?
As many edges that its base has
There is one face on the base and 4 round the edge (from each bottom edge to the top vertex) giving 5 faces in all.There are 4 edges round the square base and one edge from each of the 4 vertices of the base to the top vertex, giving 8 edges in all.There are 4 vertices round the square base plus another one at the top, giving 5 vertices in all.As a check, this obeys Eulers formula: Faces + Vertices = Edges + 25 + 5 = 10 = 8 + 2
Two. The top 'edge' or point, and the bottom edge defining the circle or ellipse of the base.
400 square inches
One and it is its base
A square base pyramid has 8 edges and 5 vertices.
