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.
1/2*p*w^2*l
You will need to find the surface area of each face and add them together.
Surface Area = 2 × Base Area + Base Perimeter × Length
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
It depends on the size of the triangular prism, but depending on the side of the prism you use the triangle area formula to find it or the rectangle area formula to find it.
First you find the area of the surface and then you multiply that by the height of the prism. Example if the surface area is 6cm and the height is 5cm then the volume is 6 time 5 cm cubed. So 30cm Cubed. All volume is measured in cubic cm or m . Cool.
the defnition of find the surface area of triangular prism and cylinder
A prism is a 3-dimensional figure, which has a volume, so I presume you mean surface area. The simple answer is you find the area of each face (both pentagons and all 5 parallelograms), and then add them together. If you don't know how to find the area of one or more of the faces, that is a separate question.
The cross section area times the height (or length depending on how you look at it). What is the area of the pentagon? how high/long is the prism?
1/2*p*w^2*l
surface area of a rectangular prism is the formula: 2lw+2wh+2lh
To find the surface area of an equilateral triangular prism you take the area of the rectangular sides and the triangular bases and add them up and your done.
You will need to find the surface area of each face and add them together.
The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
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 :)
A prism with an n-sided base will have 2n vertices, n + 2 faces, and 3n edges. A pentagonal prism has 15 edges.
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.
