Surface Area of Prisms and Rectangles

The video tutorial teaches students how to calculate the surface area of different types of prisms, including cubes, rectangular prisms, and triangular prisms. It explains the concept of surface area as the sum of the areas of the bases and lateral faces of a solid figure. The tutorial provides step-by-step examples for each type of prism, demonstrating how to unfold the figures to find their nets and calculate their surface areas using specific formulas.
