Best yield from table

Hi,

I have a table with 2 columns for raw material (Length and Width) and i have two seperate cells for product size also called length and width. What i'm trying to do is input my product size which will then return the best fit raw material by the least amount of waste. This would be applicable to multiples. For example:

Product Size (input)
lenght Width
600 300

Raw Material Size (table)
Length Width
500 230
1220 310
1000 310
1900 350
1850 310

Result
Length Width
1220 310

The above result would be the correct answer as you would get 2 products from the one sheet of raw material with the least amount of waste. Hope this makes sense

I would really appreciatre some help/advice. I've attached my workings so far.

Thanks in advance
