The answer must be
![120\quad m{ m }^{ 2 }](https://tex.z-dn.net/?f=120%5Cquad%20m%7B%20m%20%7D%5E%7B%202%20%7D)
since the triangular pyramid has 4 faces and each has an area of 30
![m{ m }^{ 2 }](https://tex.z-dn.net/?f=m%7B%20m%20%7D%5E%7B%202%20%7D)
we should multiply that by 4 , so :
That's the answer and how you do it.
