Calculating Window and Door Trim

I'm installing 2 1/4" x 84" casing around 6 windows and a door. 4 of the windows are 47" x 47," the other 2 are 36" x 47" and the door is 82" x 36". Since I will be ordering the 2 1/4" x 84" pieces on line for delivery, how many of these pieces will I need?

Thanks.

Following is my math assuming no splicing and 45 degree cut corners.
FYI : The door side trims will be too short.

4 @ 47X47 = 16 pieces
2 @ 36X47 = 6 pieces
1 @ 82X36 = 3 pieces

Total = 25 pieces plus a few in case you screw up or get bad pieces,

Thanks. It looks like I'm going to have a lot left over.

It would be better if you could get 9' pieces. You would only need 14pc.

Good idea. I'll check around but most places that's the max.

I can't find 9' but I found 10' which is a standard size. How many of those? Thanks.

You seem to have figured that out, yes.
