[mod idea, but not request] "Realistic" dynamic matherials price of the buildings

[grumblerbear]

If u create building, u pay same weight for difference matherials with different density, and natural tiles have the same weight for the same volume, example 1 cm2 of Aluminium weigth 2.7 gramm, of steel — 7.7-8 gramm, of gold — 19.3 gramm

I know about many unrealistic moments from the point of view of physics, chemistry, but, in part, the game sometimes gives realistic knowledge of the melting temperatures, why not improve the game in this regard?

if the weight of the consumable depended on the conditional volume of the building, the gameplay could be more "educational" and interesting. Maybe. Or not.
