Surface Area of Prisms and Cylinders

The video tutorial covers the surface area of prisms and cylinders, starting with definitions and components of prisms, such as bases and lateral faces. It explains how to calculate the surface area of prisms using examples of pentagonal and rectangular prisms. The tutorial then shifts to cylinders, describing them as circular versions of prisms and detailing how to calculate their surface area. Finally, it addresses solving for missing dimensions when given the surface area, using both prisms and cylinders as examples.

What defines a prism?

• A shape with only triangular faces

• A polyhedron with two congruent faces in parallel planes

• A solid object with a circular base

• A three-dimensional object with only one base
