Answer:
S = 85cm^2
Step-by-step explanation:
The surface area of a square pyramid is given by the following formula:
![S=2hb+b^2](https://tex.z-dn.net/?f=S%3D2hb%2Bb%5E2)
where it has taken into account the sum of the area of a square and four triangles:
![4(\frac{hb}{2})+b*b=2bh+b^2](https://tex.z-dn.net/?f=4%28%5Cfrac%7Bhb%7D%7B2%7D%29%2Bb%2Ab%3D2bh%2Bb%5E2)
h: slant height = 6cm
b: base = 5cm
By replacing in the formula you obtain:
![S=2(5cm)(6cm)+(5cm)^2=85cm^2](https://tex.z-dn.net/?f=S%3D2%285cm%29%286cm%29%2B%285cm%29%5E2%3D85cm%5E2)
hence, the surface area is 85cm^2
