Lateral Surface Area of Prisms

The video tutorial covers the eighth-grade concept of surface area, focusing on the lateral surface area of a triangular prism. It uses a problem from the 2016 STAR test to demonstrate how to calculate the lateral surface area by adding the areas of the prism's rectangular faces. The tutorial explains the formula for lateral surface area as the perimeter of the base times the height, providing a step-by-step breakdown of the calculation process.

What is the primary focus of the video tutorial?

• Calculating the volume of a triangular prism
