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.
Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.
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.
you calculate the area of one side, then multiply it by three.
The surface area of a rectangular prism is the sum of the length times the width of its three pairs of faces. A triangular wedge is half of that.
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.
2*area of triangular faces + perimeter of triangle*length of prism (not prisim).

You have to find the areas of each individual triangle's area and add them all up together.
Work out the area of each of the 5 nets and then add them together
find the area of all the faces then add them all up. this is how you get surface area and there isn't any formula for it
