The surface area of the triangular pyramid can be calculated by adding the areas of all four triangles:
3 square meters + 3 square meters + 3 square meters + 3 square meters = 12 square meters
Therefore, the surface area of the triangular pyramid is 12 square meters.
Use the image to answer the question.
An illustration shows a net diagram of a triangular pyramid. The diagram shows a large triangle that is formed by 4 identical smaller triangles. An inverted triangle is the central figure inside the large triangle. Its sides are indicated by 3 dashed lines. The three vertices of the dashed line triangle touch the center of the three edges of the larger outer triangle. The 3 dashed line edges form the bases of the other 3 triangles. Each triangle represents a face of the tetrahedron. All 4 triangles have an area measuring 3 square meters.
