Thread: a right hexagonal prism

i have a right hexagonal prism
and i need to find the SA and the volume for it
what formula do i use?
a regualr prism formula?
thanks
my test is tomorrow in the morning

Please don't bump your post. People will help if they can


The Volume is the area of the base multiplied by the height



The area of a Regular hexagon(all sides and angles equal) with side length l is

The surface area is given by the formula



where l is the side length of the hexagon and h is the height.

I hope this helps

Good luck.

Hello, shilo!

I assume your exam will not include such a sloppy question . . .

Code:

         * - *
      *    A    *
      |  * - *  |
      |  |   |  |
      |  |   |  | h
      |  |   |  |
      |  |   |  |
      *  |   |  *
         * - *

We know nothing about the hexagon.
We must be given its perimeter , and its area
. . (or be given enough information so we can find and .)

The height is perpendicular to the two hexagonal bases.


The surface area consists of the top and bottom: .
. . and the lateral area: .

Therefore, the total surface area is: .


The volume is (area of base) × (height): .
