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.
first u find the perimeter and then u get the base the u have to find the area of the base and that the gives u b the base of a prism
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
12 the base times the height
You look at the edge of the triangular prism and count the points
The same way you find the perimeter of a rectangle, add the side lengths
2*area of a base + length*perimeter of base.
First you find the area of the base which is a pentagon. Then you multiply it by the height. So base times height equals volume.
Well [ph] is the first step which is perimeter times height. What you do is you multiply the height by the base. With that answer you multiply the number of sides of the shape which is 5 sides and the heighth. That is how you findd you answer :)
Surface Area = 2 × Base Area + Base Perimeter × Length
width*height*length=perimeter of a rectangular prism! :)
Add up all of the lengths of the edges adjacent to one of the bases.
