Relational Geo-shapes (Large Shapes)

Set of 17 pieces of 3-Dimensional Geometric Shapes, consisting of prisms, pyramids, cones, cylinders, and spheres. All the shapes share a common height of 10cm (except one shape which is 5cm x 5cm x 5cm to allow relative comparison).  The common height makes the relative comparison more meaningful.

This set is a similar but significantly larger version of K469. There are 17 shapes, each can be filled with water, sand or another grain.  The see-through clear plastic makes the comparison effective and easy.
