How do you find the surface area of a pentagonal 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.


What is the perimeter of the base of a pentagonal prism is 45 cm what is the width of the rectangular side of that prism?

To find the width of the rectangular side of a pentagonal prism, we need to know the height of the prism or additional dimensions related to the rectangular sides. The perimeter of the base, which is the pentagon, is 45 cm, but without the height or specific dimensions of the rectangular sides, we cannot determine the width. If you provide the height or more details, I can help you calculate the width.
