speaker stand filler follow up


Am hoping some mathematician can assist me in figuring out how much filler I need. PMKably recommended midway usa for lead shot, and they have it! Now I need to determine what guage to buy and how much. My spekaer stands are a triagular column - 20 inches high and the triangles are 4 inches on each of the three sides. Any thoughts on how many pounds of shot I will need to fill these up? Thanks for the help.

By my calculations, you need 140 cubic inches per stand.

The area of a triangle = base x height / 2

A 4" equilateral triangle has a height of 3.5"

4" x 3.5" = 14" / 2 = 7 sq in (area of triangle)

Multiply area x height to obtain volume:

7 x 20 = 140 cubic inches per stand

I don't know how you would convert this to pounds of shot (without knowing the specifics of the material), but it should help.
