SOLUTION: I am trying to get the cubic weight of a hollow cylinder. I used the formula for volume of a hollow cylinder {(sqrt/4)x h x (OD^2-ID^2)}. Since I have the weight per linear foot,

Question 460637: I am trying to get the cubic weight of a hollow cylinder. I used the formula for volume of a hollow cylinder {(sqrt/4)x h x (OD^2-ID^2)}. Since I have the weight per linear foot, do I divide the weight per linear foot by the cubic volume to get cubic weight?

--------------
If you have the weight per foot, multiply that by the # of feet in the length.
pounds/foot x feet = pounds

PS There is no such thing as "cubic weight", it's just weight. Same for volume, it's not cubic volume. The volume can be in units of cubic feet, cubic meters, cubic yards, etc, but it's just volume.
