The net of the rectangular prism shows that there are 6 faces: 3 pairs of identical faces. Each pair of identical faces are rectangles with dimensions 3in by 4in, so the surface area of one pair is 3in x 4in = 12in^2. Since there are 3 pairs of identical faces, the total surface area of the rectangular prism is 12in^2 x 3 = 36in^2.
Therefore, the surface area of the rectangular prism is 36 in^2.
