2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
okay, to find the base of a triangular prism you just b = 2a/h (base = 2 * area/height)
To find the surface area of an prism you must do the following: EXAMPLE: S.A.( SURFACE AREA) and L.A.(LATERAL AREA) S.A.=L.A. +2B S.A.=113 +2 (28) S.A.= 113 + 56 S.A.=169 IN.2( THE 2 MEANS SQUARE ROOT)
use the net to find the lateral area of the prism 3m 6m 3m 6m 15m
L=PH L=PH Lateral Area= (Perimeter of the base)(the height of the figure)
The lateral area [L] of a right prism with base perimeter [P] and height [h] is L=Ph.
the defnition of find the surface area of triangular prism and cylinder
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.
Assume that a = apothem length of the triangular prism, b = base length of the triangular prism, and h = height of the triangular prism. The formulas to find the surface area is SA = ab + 3bh.
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.
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).
The lateral area of a triangular prism is found by computing the perimeter of the triangular base (sum of the three sides) and multiplying it by the height of the prism. If the triangular base has sides of length s1, s2, and s3, and the height of the prism is h, then each lateral face of the prism would be a rectangle. The area of one face of the prism would be (s1 x h), the area of the second face of the prism would be (s2 x h), and the area of the third face of the prism would be (s3 x h). So the three lateral faces would have a total area of (s1 x h) + (s2 x h) + (s3 x h), or equivalently (s1 + s2 + s3) x h; i.e., (the perimeter of the triangular base) x (the height of the prism).
If the bases have sides of length a, b and c units and the length of the prism is d units thenlateral area = (a+b+c)*darea of base = sqrt{s*(s-a)*(s-b*(s-c)} where s = (a+b+c)/2Then total surface area = lateral area + 2*area of base.

You look at the edge of the triangular prism and count the points
It is not possible to answer the question because the information which is provided does not enable you to distinguish between a "fat" but short prism or a thin long one.
You find the area of each of the four triangular faces of the prism and add them together.
