Explanation:
The pyramid's surface area = base area + 4 x plane area.
Base area
Base area
Plane area, we have to find the length from peak to the mid point of side.
Since the length from mid point of side =3, and the height =3, therefore, the length from peak to the mid point of side
The area of one plane
Total plane area
Total area of pyramid
