4. Circulate the Air. Circulating the air can also help reduce the condensation on your windows. So, use your ceiling fans even in the winter. You want the fans to rotate in a clockwise direction to push warm air off of the ceiling back down to the floor.. Circulate the Air.

An octagonal prism has 10 faces. The octagonal prism can be seen to have ended shaped like octagons. That's an 8-sided figure. is a 3-dimensional form, and if it has octagons on each end, it is going to have 8 faces. That's a face for each side of the octagon. The 8 faces of the body of the prism are added to the two faces (one on each end) for a total of 10 faces. (The illustration is a pentagonal prism.). An n-gonal prism has n+2 faces.
There are eight vertices in a rectangular prism. Any prism is a three dimensional figure; it has two bases and is formed by rectangles connecting the edges of each base to each other. So in the case of a rectangular prism is a rectangle. Thus, the number of faces of any prism is the number of edges of the base + 2. Also, the number of vertices is just the number of vertices of the base shape, times two. A rectangular prism has eight vertices because the base (a rectangle) has four vertices. That times two is eight.
