How do you find the lateral surface area and total surface area of a pyramid?

To find the lateral surface area of a pyramid, calculate the area of each triangular face and sum them up. For a regular pyramid, this can be done using the formula ( \text{Lateral Surface Area} = \frac{1}{2} \times \text{Perimeter of the base} \times \text{Slant height} ). The total surface area is then found by adding the area of the base to the lateral surface area: ( \text{Total Surface Area} = \text{Lateral Surface Area} + \text{Area of the base} ).
