The surface area of a triangular prism is equal the sum of area of the triangle on 3 sides and the the area of the base triangle. The formula for the triangle is 1/2*height times base of that triangle.

If the prism has all sides equal, then just find out the area of 1 triangle side, then multiply that by 4.

If you don't understand my instruction above, then here:
For all equal side of triangular prism

SA = 4*(b*h/2)

in case you get somewhat of paper and fold it right into a triangular prism, you'll see that the area of the oblong faces is basically the fringe of the triangles on the right, circumstances the dimensions. If the area of the triangles on the ends is seen element of the area, then you extremely ought to upload that in, too.
