[TowerTalk] deep base for MA-550

[Jerry Keller]

There are 27 cu ft in 1 cu yd (3 ft x 3 ft x 3 ft)...so 2.5 ft x 2.5 ft x 5.0 ft = 31.25 cu ft... divided by 27 cu ft = 1.157 cu yd.  Jerry K3BZ

  Hold on here. Isn't the formula pi*r^2*h=v? My calc says about 78.5 cu ft 
  or 2.9 cu yds.

  Oh, I'm sorry. I just noticed the @stanford.edu.
