Answer:

A Newman projection for cyclohexane is two Newman projections joined together.

Explanation:

For the chair form, view the diagram so that the carbon atom nearest to you (#"C-6"#) is "up", #"C-2"# is "behind" #"C-1"#, and #"C-4"# is "behind" #"C-5"#.

Draw side-by-side projections of the #"C1-C2"# and #"C5-C4"# bonds.

Join the two diagrams with the front carbon (#"C-6"#) at the top and the rear carbon (#"C-3"#) at the bottom.

Add the groups (here they are #"H"# atoms) to the bonds extending from the Newman projections.

For the boat form, repeat the process.

The difference in this case is that the rear carbon (#"C-3"#) is "up" and the bonds are eclipsed.
