Please help with shipping costs (All items will be from S. Korea)

Hello, I'm trying to figure out how much should I charge per volumetric weight of a product.

All items will be from S. Korea and the shipping fee is 154,000 KRW for a 730*520*730mm

In my country, they usually charge the volumetric weight using this formula LxWxH(cm) / 3,500

So first, I converted the dimensions to cm

73*52*73 / 3,500 = 79KG (volumetric weight)

Now this is where I'm stuck, how do I know how much is the shipping fee per volumetric weight in USD?

If 1USD = 1,180KRW, 154000KRW is 130.51USD

The answer I came up with is 1.652USD per KG. Is this correct? I'm sorry it must look pretty simple but I'm really uncertain.

If this is correct, then..
If the product's dimension is 13x25x17.7cm, I should charge 2.71USD for its shipping fee?

Yes, you have done the problem correctly. For problems like this it is sometimes nice to look at units: What you have is cost of 154000 KRW per (277108/3500) VW (volumetric weight). Since 1USD = 1,180KRW we can replace the KRW by (1/1180) USD to get 154000*[(1/1180) USD]/[277108/3500) or, letting the KG stand for the volumetric weight, a cost of
\(\displaystyle \dfrac{154000\, KRW\, \dfrac{1\, USD}{1180\, KRW} } {79.1737\, KG}\, = \)\(\displaystyle 1.648 USD\, per\, KG\)

BTW: The reason for the discrepancy in our answers is your use of the 79 KG and mine of the 79.1737 KG.
