MHB Need help with a work related math problem

[semaxus]

Hello guys, I confess that I absolutely suck at math. Unfortunately my boss handed me what is basically a math problem I got to solve, and I have no idea how to do it cause of lack of my math skills. I am hoping someone can help me with this or I'm screwed.

Co basically I've got this table in excel, where X (row) is a width and Y is a height (column) of a wooden sauna cabin, the X;Y is the price for a sauna with said dimensions. I need to find a relationship between the size of the sauna and the price And formulate ani equation. I can't seem to find it, the price seems to grow non linearly, I can't seem to find any coeficient. Again, I suck at math, maybe solution is simple, but I just don't see it. Can anyone help me please?

Table Is at this link https://ibb.co/fGrxSvf . Thanks for any help!

You have the information in a table form where you can easily read off the information you need. I can't imagine why you would want a "formula" that either would be extremely complex (Generally speaking "n" data points can be calculated by a polynomial of degree n-1. Here you have a large number of data points!) or is only approximate, if not both.
