Answer: A=5t2 /4 (tan 54)
Explanation
----
The base of a pentagonal prism is a pentagon. To find that area, we start with the general area of a regular polygon. Let abe the apothem and P be the perimeter of the polygon. The area, A=1/2Pa
Now let t be the length of any side of the pentagon and substitute in for the apothem and we have:
A=1/2 x 5t x t/2(tan 54)
or A=5t2 /4 (tan 54)

What is the volume formula for a pentagonal prism?
Volume = (base area) x height.
Volume of pentagonal prism?
Area of pentagon * length of prism.
Why is the formula for finding the surface area of a rectangular prism helpful?
its not i dont no why
What is the general formula for finding the volume of a prism or cylinder?
Area=Bh when B=area of the base, and h=height of the prism/cylinder
What is the formula for a pentagonal prism?
There is no single formula. The answer depends on what the formula is for: the volume, surface area, numbers of faces, edges, vertices and so on. And since you have not bothered to provide that crucial bit of information, I cannot provide a more useful answer.
