 June 14, 2012, 17:10 Help with resolving a 1000 year old dilemma #1 New Member   Fiaz Join Date: Jun 2012 Posts: 1 Rep Power: 0 Sponsored Links I'm new to the forum and my query might seem very basic, but would appreciate an answer. I came across the works of some medieval scholars who set to determine what is the minimum depth of water that extends across an area 10 cubits x 10 cubits that if you were to scoop water from it, the ground underneath it would NOT appear. A cubit (elbow to fingertip) for the purposes of this calculation is taken to be 46.2cm. Hence, 10 cubits2 = (10 x 46.2cm)2 = a surface area of 213,444cm2. I would appreciate if someone could answer what would be the minimum thickness for the film of water to hold across this entire surface?
