Answer:
![62.4$ cm^2](https://tex.z-dn.net/?f=62.4%24%20cm%5E2)
Step-by-step explanation:
The net of the triangular pyramid is attached below.
Since each of the faces is an equilateral triangle of side 6cm, the base of the pyramid will also be an equilateral triangle of side lengths 6cm .
In the equilateral triangles
Therefore, the surface area of the pyramid formed from the net shown
= 4 X Area of One Triangular Face
![=4 (\frac12 \times bh)\\=4 (\frac12 \times 6\times 5.2)\\=4(15.6)\\=62.4$ cm^2](https://tex.z-dn.net/?f=%3D4%20%28%5Cfrac12%20%5Ctimes%20bh%29%5C%5C%3D4%20%28%5Cfrac12%20%5Ctimes%206%5Ctimes%205.2%29%5C%5C%3D4%2815.6%29%5C%5C%3D62.4%24%20cm%5E2)
