Calculating Surface Area of Prisms

This video tutorial explains how to calculate the surface area of a right triangular prism using a formula. It begins with an introduction to the method, followed by a detailed explanation of calculating the lateral surface area by summing rectangles. The video then derives the formula for surface area, explaining the significance of the perimeter and height. The formula is applied to a specific example, demonstrating how to find the total surface area. The tutorial concludes with a practical example calculation, resulting in a final surface area measurement.
