The use of mitre box is to hold pieces while cutting in the exact angel you need. Make joint cuts with a pre-molded trim ( 45 degrees angle)

First you should take the acute measure of the room. Allow an extra spaces for losses derived from cutting.

Always make the piece shorter.

Join the pieces at 45 degree angels

If the moulding piece does not cover the entire extension of the room,join in the suitable joint

Don’t commit any mistake, they are visible if made in the corners. To avoid errors, cut pieces slighter shorter, so they end before the corner.

Small pieces can be added to the corners to finished them. If you don’t like that, try extra care when fitting the pieces and fill any space with a wood putty, after that sand it with care

Hammer finishing nail at the end,at different levels on the adjoining piece. Doing this last you will prevent any crack of the trim.

You can glue pieces,too.Trim cracking can occur but you can diminish the risk covering the hammered surface with wood or plastic while you are nailing. The nail will compress internally the wood and that will avoid the crack on the surface.To work free hand or with clamps in the adjustments you need to make, use a code saw.
