I think it is eight because of the seven points one on each side of the faces and one on top.

How do you find out the number of edges on a shape?
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
How many faces has an octagonal pyramid?
An octagonal pyramid has nine faces. It also has nine vertices and 16 edges. You can find the volume of this pyramid by using the formula that the base 'B' multiplied by the height 'h' must be divided by three.
How many vertices and faces of 3D shapes?
You can find a polyhedron with any number greater than 4 of vertices or faces. However, a torus, ellipsoid, sphere, paraboloid, hyperboloid are all standard shapes with no vertices. Cylinders, too, have no vertices. And there are many completely random shapes - a lump of putty, for example, which will have no vertex.
What is the formula to find the area of a pyramid?
first you find the area of the base and then you find the area one side of the pyramid an you time it with 3 if it is a triangular pyramid or 4 if it is a square pyramid
How do you find diagonals in a polygon?
Suppose a polygon has n vertices (and sides). From each vertex, a diagonal can be drawn to all vertices, excluding itself and the two adjacent vertices. So n-3 diagonals can be drawn from each vertex. Multiplying by the full complement of n vertices gives n(n-3). However, as things stand we have counted each diagonal twice: once at both ends. Dividing by two gives the actual number of diagonals. number of diagonals = n(n-3)/2
How can i use a graph to find the number of vertices in a octagonal pyramid?
The number of vertices in an octagonal pyramid is 9, irrespective of any graph.
How many eadges does a pyramid have?
It depends on the base of the pyramid. To find it, add the number of edges of the vertices is of the base to its number of edges. Example: for a square pyramid, there is 4 vertices and 4 edges in the base. The Edges of the pyramid is then 4+4 which equals 8.
How is the number of vertices for a pyramid related to the name of the pyramid?
Subtract 1 from the number of vertices. Find the name of the polygon with that many sides. The pyramid has that polygon as its base. So, for example, 7 vertices. Subtract one and that gives 6. A six sided polygon is a hexagon. So the shape is a hexagon based (or hexagonal) pyramid.
How many vertices does a pyramid have whose base is an n-gon?
n+1The above formula is how to find the number of vertices in an n-gon.
How find number faces on pyramid?
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
How many corners does the heptagonal pyramid have?
A heptagon is a figure with 7 sides. Also, if by corner you mean edges, we can find that. There's the edges of the heptagonal base. So there's 7. Then we have the edges of where the lateral faces meet each other. There's another 7. You have 14 edges in a heptagonal pyramid. If, in fact, you meant "corners", then we add in the vertex (or apex) of the pyramid. Then you will have 15 "corners".
How many corners are on a hexagonal pyramid?
To find the number of vertices on any pyramid, take the number of corners on the base and add 1 (for the top) A hexagonal based pyramid has 7 vertices (6 for the hexagon, 1 for the top) I suspect you might mean "hexagonal prism" though. In which case, for prisms, you double the number of corners in the 2D shape. A hexagonal prism has 12 vertices (6 for the hexagons at each end.)
How many faces vertices edges does a heptagonal prism have?
I don't want the answer. I want to know how to find the answer for myself.
How do you find a triangular pyramid?
A triangular based pyramid is a tetrahedron which has 4 faces, 6 edges and 4 vertices
How do you find out the number of edges on a shape?
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges.
Find the mean of the y-coordinates of the vertices?
It is the sum of the y-coordinates of the vertices divided by the number of vertices.
How many faces has an octagonal pyramid?
An octagonal pyramid has nine faces. It also has nine vertices and 16 edges. You can find the volume of this pyramid by using the formula that the base 'B' multiplied by the height 'h' must be divided by three.
