The amount of material remaining on a roll 
20161111 

Yoh pose la question :
Question from Yoh:
Hello,
I am trying to find impressions on a roll (either full roll or partial).
Let's say I have the following information.
 Outer Diameter of roll
 Inner Diameter of roll (cardboard core)
 thickness per layer
 Each cut off length (impression length)
Now let's say a roll has a 40in outer diameter, the cardboard core has a 3.75in diameter and a thickness of .002. Each impression has a cut off of 14inches.
With this the roll will have approximately 2,700 impressions. How would I find the remaining impressions if the outer diameter of the roll is only 6.5inches?
Thank you. Penny Nom lui répond. 





Cubic feet and gallons

Leonard pose la question : Every conversion I find to convert a cubic foot to a gallon is in liquid.
Question, how would 1 cubic foot convert to gallons in dry measurement?
Example say you have 1 Gallon of packing peanuts how many cubic feet would that be?
I can do this and have done it for the heck of it, I took a box 12x12x12 inches, which is a cubic foot,
filled it with packing peanuts the tried to fill a 1 Gallon container, that amount almost fills a 1 gallon
bucket twice.
I even ask a math teacher and was told that 1 cubic foot equaled 7.481 gallons,
then I said that is liquid, teacher ansered yes, then i ask what about dry and got
a response of I do not know. Harley Weston lui répond.
