Calculating Surface Area of Prisms and Cylinders

This video tutorial covers how to calculate the surface area of various 3D shapes, including prisms and cylinders. It begins with an explanation of surface area concepts for both 2D and 3D shapes. The tutorial then provides step-by-step instructions for calculating the surface area of prisms with triangular bases, cylinders with circular bases, and hexagonal prisms. Each section includes detailed examples and calculations. The video concludes with a summary and an invitation to subscribe for more math tutorials.
