Nine faces: 1 square, 4 identical rhombuses and 4 identical triangles. We rebuilt it from a net in the Nada Junior High School entrance exam. The base is a 6 cm square, a 5–5–6 cm triangle stands on each of its sides, and 5 cm rhombuses join them up to the top. The edge lengths alone do not fix the rhombus angles: this is the only shape whose height is 8 cm with the square at the bottom.
