Understanding an Octagonal Prism

In this video, Mr. Jay explains how to determine the number of faces, edges, and vertices of an octagonal prism. He begins by counting the faces, identifying a total of 10. Next, he counts the edges, finding 24 in total. Finally, he counts the vertices, which amount to 16. The video concludes with a summary of these properties, providing a clear understanding of the geometric structure of an octagonal prism.

What is the main topic discussed in the video?

• The properties of a triangle
