Exploring Surface Area of Prisms and Cylinders

This video tutorial focuses on the surface area of prisms and cylinders. It begins with basic definitions of polyhedrons, prisms, and cylinders, and explains the differences between right and oblique prisms. The tutorial then covers how to calculate lateral and surface areas, providing formulas and examples for both prisms and cylinders. The video concludes with practice problems to reinforce the concepts learned.

What is a polyhedron?

• A two-dimensional figure with polygonal faces

• A three-dimensional figure with polygonal surfaces

• A three-dimensional figure with curved surfaces

• A two-dimensional figure with curved edges

What distinguishes a right prism from an oblique prism?

• The number of bases

• The color of the lateral faces

• The alignment of the sides at right angles

• The shape of the base

What is the base of a triangular prism?

• A rectangle

• A pentagon

• A triangle
