Calculating Surface Area of a Hexagonal Prism

The video tutorial explains how to calculate the surface area of a hexagonal prism. It begins by identifying the base of the prism and then introduces the formula for surface area, which includes the lateral area and the area of the base. The tutorial provides detailed steps to calculate the lateral area by finding the perimeter of the base and multiplying it by the height of the prism. It also explains how to find the area of the hexagonal base by decomposing it into equilateral triangles. Finally, the video combines these calculations to find the total surface area and includes a practice problem for reinforcement.

What is the formula for the surface area of a prism?

• Surface Area = Lateral Area - Base Area

• Surface Area = Base Area / Lateral Area

• Surface Area = 2 * Base Area + Lateral Area

• Surface Area = Base Area + Lateral Area
