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.
