Answer:
- When all side faces are the same:
Surface Area = (Area of the Base) + 1/2 × Perimeter × (Slant Length)
- When side faces are different :
Surface Area = (Area of base) + (Lateral Area).
Step-by-step explanation:
A pyramid is formed by connecting a base to a top. There are no curves in a pyramid, the base is a polygon and all other faces are triangles.
There are many types of Pyramids, and they are named after the shape of their base.
We have Triangular Pyramid, Square Pyramid, Pentagonal Pyramid, and so on.
The Surface Area of a Pyramid.
We need to consider the two cases:
- When all side faces are the same:
Surface Area = (Area of the base) + 1/2 × Perimeter × (Slant Length)
- When side faces are different :
Surface Area = (Area of base) + (Lateral Area).
We consider the Area of Base because a pyramid's base varies, as I have explained earlier. It can be a square, a triangle, a pentagon, and so on.
