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)
Volume = (base area) x height.
Area of pentagon * length of prism.
its not i dont no why
Area=Bh when B=area of the base, and h=height of the prism/cylinder
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
The fact that it's a prism has nothing to do with the area of the base. See the attached Related Link for your formula.
Volume = (base area) x height.
There must be a typo in this question, "Why does the formula for finding the surface area of arectangular prism is helpful?" What does that even mean?
Area of pentagon * length of prism.
surface area prism = 2 × area end + total area side = 2 × area end + perimeter end × length of prism The information given to you will allow you to work out the area of one pentagonal end, and the perimeter of the pentagonal end.
its not i dont no why
It depends on what information you have.
It depends on the prism. Is it a triangular prism, a rectangular prism, a pentagonal prism... etc..
Area=Bh when B=area of the base, and h=height of the prism/cylinder
Volume = area of pentagon x length of prism.
I am not sure that a rectangular prism is in any position to care!
Area of Base x Height
