Attributes of 3D Shapes
Discover how to describe 3D shapes by counting their faces, edges, and vertices, and see how these attributes compare across common solids.
What You'll Learn
Identify the three main attributes of a 3D shape: its faces, edges, and vertices
Recognize that a face is a flat or curved surface, an edge is where two faces meet, and a vertex is a corner point
Count faces, edges, and vertices accurately for solids such as cubes, rectangular prisms, pyramids, cones, cylinders, and spheres
Compare attributes across different solids to explain why some shapes roll and others stack or slide
Apply attribute vocabulary to describe and sort real-world objects by their 3D shape properties
