Delivery fees

Hi, I am trying to understand setting up different fees in my Woocommerce settings.

So, I am selling a few different products, each has its own price based on the box size and weight.
Also, customers can buy 5 of the same products, so I need my shop to charge accordingly.

I.e., one product costs me ￡25 to ship to the USA, but 5 products would cost me around ￡90, not 5 x ￡25.
How to set this up, please?

Many thanks
Boris
