Length of prism * perimeter of triangular face.

Volume of a triangular prism = cross-section area times length
A triangular prism is a three-sided prism with three faces joining corresponding sides. The formula for its surface area is SA = wh + lw + lh + ls, where l=length, h=height, w=width and s=side.
A triangular prism can have a square or triangular base.
Triangular prism = 2 triangles + 3 rectangles.
Length of prism * perimeter of triangular face.
triangular prism- formula: Abh(area of the base * height)
The answer depends on the formula for what characteristic of the prism.

Find the area of a triangular section, 1/2bh, and then multiply by the length of the 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.
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.
A triangular prism can be thought of as a stack of triangles. Then the volume is equal to the area of the triangular base multiplied by the height of the prism, or 1/2 length * width * height.
2*area of triangular base + perimeter of triangle*length of prism.
