Answer:
The surface area of the model pyramid is ![451\ in^{2}](https://tex.z-dn.net/?f=451%5C%20in%5E%7B2%7D)
Step-by-step explanation:
we know that
The surface area of the pyramid is equal to
![SA=B+LA](https://tex.z-dn.net/?f=SA%3DB%2BLA)
where
B is the area of the base of the pyramid
LA is the lateral surface of the pyramid
<em>Find the area of the base B</em>
-----> is a square
<em>Find the lateral surface area of the pyramid LA</em>
we know that
The lateral surface area is equal to the area of its four triangular faces
![LA=4[\frac{1}{2}(11)(15)]=330\ in^{2}](https://tex.z-dn.net/?f=LA%3D4%5B%5Cfrac%7B1%7D%7B2%7D%2811%29%2815%29%5D%3D330%5C%20in%5E%7B2%7D)
<em>Find the surface area of the pyramid</em>
Substitute the values
![SA=121+330=451\ in^{2}](https://tex.z-dn.net/?f=SA%3D121%2B330%3D451%5C%20in%5E%7B2%7D)
