Lateral Surface Area and Triangles

Mr. Sal explains how to calculate the total surface area of a pyramid with a hexagonal base. The video breaks down the problem into manageable parts, first calculating the area of the hexagonal base by dividing it into triangles, then finding the lateral surface area by considering the lateral triangles. Finally, the total surface area is obtained by summing these areas. The video emphasizes careful calculation and rounding to the nearest tenth.
