    If the base has side length s, the total area is a square and four triangles with height 12 (the slant height):
s^2 + 4 * (1/2)(12)s = s^2 + 24s
Now just solve for s and recall that the volume is
1/3 Bh = 1/2 s^2h
where h^2 = 12^2 - (s/2)^2
    
s^2 + 4 * (1/2)(12)s = s^2 + 24s
Now just solve for s and recall that the volume is
1/3 Bh = 1/2 s^2h
where h^2 = 12^2 - (s/2)^2
