Stacked Tritans

Rectangular isosceles triangles are called Tans. If you take three solid pieces and join them at their triangular or rectangular faces, you get stacked tritans or stackes triabolos. If the short sides of the triangles have the unit length and their height is h, the total volume of the pieces is 10 x 1.5 x h=15h. You can assemble prisms with a height of 3h and some other figures.
A hexagonal box to store the pieces is also provided.
