I have a REALLY old system that has 6 un-stripped wires: blue, blue & white, orange, orange & white, green and green & white. What do I do?

My answer is this; LxWxH (50+35+50+35) = total Length L=170 ft W= 16" or convert to ft = 1.33 ft H = 8" or (8/12) = .67 Ft. 170 ft x 1.33 ft x .67 ft = 151.5 Cu Ft. Since 1 Cu Yd = 3' x 3' x 3' = 27 cu ft; Divide 151.5 cu ft needed by 27 cu ft per yard = 5.6 Cu Yd.

However; note that there are codes determining the depth and width of a footing, and in most jurisdictions, this footing must be placed below the frost line for your area. Also note, depending on size of structure, some steel reinforcing bars may also be required. Please check with your local codes office before going any further - ok for a small backyard shed tho, I suspect.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
