Am I going about this right? (probably not)
You are going to build a concrete wall with a 30" diameter pipe going through it. The wall is 8'H X 10'W X 3'D.
1. Find cu ft of wall. 240 cu ft
2. Find surface area (or would it be volume?) of pipe. 3579.6 cu in or 2.071 cu ft
3. Subtract pipe from wall.
4. Order 237.929 of concrete
Thanks.
