We know that
<span>total surface area of the composite solid=surface area of the pyramid+surface area of the cube
surface area of the pyramid=4*area of lateral triangle side
area of lateral triangle side=12*9/2----> 54 in</span>²
surface area of the pyramid=4*54---> 216 in²
surface area of the cube=5*[12*12]----> 720 in²
total surface area of the composite solid=216 in²+720 in²---> 936 in²
the answer is the option
<span>936 square inches </span>
