It would have to be an oblique prism. That is one in which one of the bases has been translated or rotated with respect to the other.

What is the formula for the pentagonal prism?
I'm supposing this question is referring to volume.In which case, it's dependent upon whether you know the area of the base or not.If you do, then it is as simple asV=AhWhere V = Volume, A = Base area, h = Prism heightIf you don't know the area of the base, then we'll need to know the apothem height and average base vertex length.Say you have a perfect pentagonal prism, where all base vertex lengths are the same, then good, you can just use that one length as your L variable, which will represent base vertex length.If you do have a perfect pentagonal prism, skip this paragraph. If you have a pentagon where three sides are 3cm and two are 5.5cm, then you have to average them. 3 + 3 + 3 + 5.5 + 5.5 = 20. 20 / 5 = 4. Your average base vertex length is 4.Now that you have your vertex length you must find the apothem height. If the pentagonal prism you're working with is a tangible object or direct scale drawing, you'll be able to locate the apothem height. To do this, find the center of one of the base vertices. Draw a line or scribe a mark from the center of the vertex directly out at a 90 degree angle. Do the same with another vertex. The point where the two apothems that you've drawn meet is the center. Now, find the length of the apothem, which will now be represented by S.Remember, L = Base vertex length, S = Apothem height, h = Prism height.Now, think of the prism as 5 triangles stuck together like slices of a pie. So, take the apothem height times the prism height times the base vertex length.L * S * hThis is dividing the length of the prism like the pie I talked about in the last paragraph. We now have 5 triangular prisms. So to find this volume you would do...B * H * h / 2Where B = Base vertex length, H = Height of triangle from bottom vertex to the highest point, h = Prism height.Notice I left out the / 2 in the L * S * h formula. That's the only step left for the triangular slices of prism.L * S * h / 2Now multiply your slices by five for the total prism pie!Pentagonal Prism Volume = 5 * (Vertex * Apothem * Height) / 2Hope I helped! I learned a bit while writing this too, so thanks to you I guess!

A regular pyramid has a regular polygon base and a what over the center of the base?
vertex
Does a regular pyramid have a regular polygon as its base and a vertex over the base's center?
Yes
A regular pyramid has a regular polygon as its base and vertex over the base's center?
Yes.
Any polygon can be the base of a prism?
The base of a prism can be any polygon, but the polygon face parallel to the base must be congruent. True
Can a polygon be a base of a prism?
Yes.
How do you work out the base area of a prism?
That depends on the shape of the base. A prism can have any sort of polygon for its base.
What is the parts of a cone prism?
There is no such things a combined cone prism. A cone has a polygonal shapes base with all ofthe points on the edge of the polygon rising up a certain height to one point from the center of the base polygon. A prism is two polygonal bases. These bases are connected on the edges and have a certain height.
What has a polygon for its base and triangles for its sides which meet at one vertex?
It is a pyramid
In a prism a face that is not a base of the figure and in a pyramid its faces that intersect at the vertex?
any face that is not a base is?
