Research by Alexander Jaoshvili of New York University and colleagues, published in Physical Reviews Letters in 2010,1 showed that the tetrahedron is the most efficient shape for filling a container randomly with identically-shaped objects. They found that the tetrahedra were packed tightly enough to occupy 76 percent of their containers. In comparison, randomly packed spheres fill up to 64 percent of space, while the figure for ellipsoids can be as high as 74 percent.
