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 ...

A prism has a constant cross-section throughout its length. When the cross-section is a triangle, the prism is called a triangular prism. When the cross-section is a hexagon, the prism is called a ...

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 ...

A cross section is the shape formed when a plane intersects a three-dimensional figure. Imagine slicing through a solid object with a knife; the shape of the slice is the cross section. Understanding ...

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 ...
