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.

you calculate the area of one side, then multiply it by three.

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.

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.
