Gerry, 

I’m wondering what you mean by four times larger? Do you mean four times the volume? Or four times the surface area? 

It’s not a trick question. I’m just trying to follow your argument. It’s 50 years since I did any academic physics so I’m a bit rusty. 

Warm regards from a rainy England, 

Steve G0XAR
