Abstract
The present invention provides a three-dimensional geometric puzzle having a cube element, five triangular prism elements and a parallelepiped element. Each one or all of the elements of the puzzle are capable of being oriented such that they have a thickness equal to the length of an edge of the face of the cube element. The elements can also be juxtaposed in a predetermined fashion to form various geometric solids, such as a parallelepiped having a square face and a height equal to the length of a side of an edge of the cube element.

A three-dimensional tangram comprising:
- a resilient cube element having a thickness and a volume and having six identical faces, each of the identical faces having four identical edges, the edges each being at least one inch in length;
- a first resilient triangular prism element having two faces identical to one of the six faces of the cube element and a thickness identical to the thickness of the cube element, and having two right angled isosceles triangle faces, and having a volume equal to one-half of the volume of the cube element;
- a second resilient triangular prism element having two right angled isosceles triangle faces and a thickness identical to the thickness of the cube element, and having a volume equal to the volume of the cube element;
- a third resilient triangular prism element having two right angled isosceles triangle faces and a thickness identical to the thickness of the cube element, and having a volume equal to twice the volume of the cube element;
- a fourth resilient triangular prism element identical to the first triangular prism element;
- a fifth resilient triangular prism element identical to the third triangular prism element;
- and
- a resilient parallelepiped element having two faces identical to one of the six faces of the cube element and a thickness identical to the thickness of the cube element, and having volume equal to the volume of the cube element.
