Question from Jim: How many cubic feet of stone will it take to fill to six inches around a 4 inch pipe in a ditch 128 ft long x 20 in wide? |
Hi Jim,
You can use our volume calculator, but you need to use it twice. Use it first to find the volume of the ditch without the pipe, that is a ditch 20 in wide by 6 in deep by 128 ft long. Then find the volume of the pipe to see mow much stone you will need to remove to make room for it.
I hope this helps,
Penny
