The Surface area of a triangle = 0.5*base*height The volume of a prism = area of its cross-section*length
Find the area of each face and add them all up.
Find the area of each face separately and then add them together for the total surface area.
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
Volume = Area of base x height

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
Here is what you need to do:Draw a net for an irregular hexagonal prism, including dimensions and glue flaps. Be sure to name each of the eight faces: top, bottom, side1, side2, side3, side4, side5, and side6. On a regular hexagonal prism, these sides will all be congruent, but on any other hexagonal prism they will NOTall be congruent.Cut out your net. Dry fold, (fold it but don't glue the flaps), to be sure that it works.On the front of a piece of notebook paper, explain in words how to find the surface area for your net, and then show the mathematics. *NOTE: You will have to cut the hexagon into shapes for which you know how to find the area, like triangles and trapezoids.On the back of the notebook paper explain how to find the volume for your hexagonal prism and then show the mathematics.DON'T use the same dimensions as the example. Yours must be irregular, (not all sides the same length on the hexagon).
The volume of any prism is worked out in the same way whether it's a hexagonal prism, circular prism or a triangular prism. You just need to times the length of the prism against the area of the cross-section.
Surface Area = 2 × Base Area + Base Perimeter × Length
