A 3D shape with all straight edges and flat faces is a polyhedron. Other 3D shapes with least one curved surface are not polyhedra. A 3D shape with regular polygonal faces, meeting at equal angles, is ...

These labs simplify the real-life conditions that affect structures (shapes), in order to illustrate key concepts. In the real world, many variables affect the strength and stability of any give shape ...

Complete this interactive activity to find out more about 3D shapes and then put your knowledge to the test. Cubes have 6 flat faces which are all the same size. Everyday things that have the shape of ...
