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 ...

3D shapes can be made from 2D shapes called nets. Watch the video to learn how 3D shapes, such as a cube, can be created from nets, an arrangement of 2D shapes. Let's talk about nets. More ...

Explains the concepts of volume for various geometric solids, including prisms, pyramids, cylinders, cones, and spheres. It details the formulas used to calculate their volumes, emphasizing the ...

The film explores different geometric shapes, focusing on cylinders, rectangular prisms, and pyramids. It describes the properties of each shape, such as the curved surface of a cylinder, the ...
