Answer: 108
Step-by-step explanation: The equation to find the surface area of a square pyramid is s^2+2*s*l.
The area of the square base is equal to s2
The area of one triangle is equal to (s × l)/2
The slant height of a square pyramid equals (l)
Since there are 4 triangles, the area is 4 × (s × l)/2 equals 2 × s × l
Therefore, the surface area, call it SA is Surface Area (SA)= s2
+ 2 × s × l
so if you plug in the numbers you get 6^2+2*6*6 which equals 108
