I have been given a problem of taking an object (I used a Cornflakes Box) and finding the optimal surface area compared to its volume (volume and ratio between sides constant)(adsbygoogle = window.adsbygoogle || []).push({});

I got:

Cornflakes Box :

Length = 25cm

Height = 36 cm

Width = 9 cm

Optimal Surface area box:

Length = 17.3 cm

Height = 43.28 cm

Width = 10.82

Overall a 90cm^2 difference in surface area.

Now I have to explain why Cornflakes would make a box with a greater surface area, thus costing more. Please help

The teacher also said something about the Golden Ratio, but i cant see any relation to this in the dimensions
