It is the sum of the areas of its four faces.

Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.
A prism is a polyhedron with two parallel bases bounded by congruent polygons and with lateral faces bounded by parallelograms that connect the corresponding sides of the bases. The height of a prism is any perpendicular line drawn from a point on one base to the other base. If the the bases' shape of a prism is a triangle, we call it a triangular prism (it has 3 faces). The surface area is the sum of the bases' area and the faces' area (lateral area).
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.

PyramidV = 1/3 bhb is the area of the baseSurface Area: Add the area of the base to the sum of the areas of all of the triangular faces. The areas of the triangular faces will have different formulas for different shaped bases.
Find the surface area of each of the four triangular faces (they need not be the same) and sum the individual areas.
There are normally three rectangular faces and so their angles are all right angles. But there are no restrictions on the angles of the triangular faces other than that they sum to 180 degrees.

A rectangular-based pyramid has 5 faces, 8 edges, and 5 vertices. To check if the numbers are right, the Euler's rule can be used. The formula is Faces + Vertices = Edges + 2. Clearly, the sum of the faces and vertices, which is 10, is equal to the sum of the edges plus 2, which is also 10.

No, there are TWO bases.
