The base has an area. It cannot be just 8 cm.
So, I assume you meant that the base is a square with sides 8 cm each.
In any case, the area is the square base (8^2) plus the area of the four triangular faces, each with base 8 and lateral height √(22^2-4^2)
Enter your answer and show all the steps that you use to solve this problem in the space provided.
