I don't think these are coming from the OW exam.............Lift bags were not covered in my OW exam.

They are pretty much the same questions I have in my IDC practice exams. The revised DM course did not have that much dive theory questions if I remember right.
 
I get that - but the question was about the lift bag moving the block off the bottom - exactly 300 l won’t quite get it to move off of the bottom:wink:
That was not the question. Read it again.
 
Haha. That is because you are not shaped as a concrete block. However, if you lay flat in a silt (assuming there is no gear to interfere with your surface to surface interaction) one may have difficulty lifting you up if you maintain you flat surface like a concrete block :)
I did get the answer right, but there are real life considerations as others mentioned that need to be taking into account
Yes you are correct, I misread your post.
