Answer:

The surface area is 156\ in^{2}  

Step-by-step explanation:

we know that

The surface area of the square pyramid is equal to the area of the square base plus the area of its four lateral triangular faces

so

SA=b^{2}+4[\frac{1}{2}(b)(l)]

where

b=6\ in

l=10\ in -----> the slant height

substitute the values

SA=6^{2}+4[\frac{1}{2}(6)(10)]

SA=156\ in^{2}
