Answer: Surface area = bh/2 + (S1+ S2 + S3)H
in general surface area of a prism is
2 × area of base + perimeter of base × H
So in particular, for the triangular prism, we have the answer above. Here is why.
So h is the height of the triangular base and 1/2(bh) is the area of that triangle. 2x that is
bh so that is where the bh part of the formula comes from.
Now s1, s2 and s3 are the sides. So (s1+s2+s3) is the perimeter of the base. Let H be the height of the prism, then we have (s1+s2+s3)H in the second part of the formula.

How do you do the volume of a triangular prism?
triangular prism- formula: Abh(area of the base * height)
What is the surface area of one side of a triangular prism?
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.
What is formula of triangular prism?
The formula is Bxh where B is the base which is the area of the triangle and h is the height of the prism.
What is the formula for finding the total surface area of a triangular prism?
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.
What is the formula of surface area of the prism triangular?
2*area of triangular base + perimeter of triangle*length of prism.
