Hi,

 

Could you please tell me what is the difference between the values we get from the following two options?

 

Volume Viewer:

Tools --> Measure Volume and Area

Tools --> Volume Mean, SD, RMS

 

Is SD means standard deviation? What is RMS?

 

In the 2nd option, we get 'Surface V and A'. What does 'Surface' mean in here?

 

Thanks,

Chinthaka.
