Definition
- Noun:
- A three-dimensional shape: A "solid figure" is a geometric object that has three dimensions—length, width, and height (or depth). It occupies space and has volume, unlike two-dimensional shapes which are flat.
Usage Examples
- Noun:
- In geometry class, we learned to calculate the volume of various solid figures like cubes and spheres.
- The sculpture was composed of several interlocking solid figures.
- Architects often use models made of solid figures to represent buildings.
Advanced Usage
"Regular solid figure": A polyhedron where all faces are congruent regular polygons and the same number of faces meet at each vertex (e.g., a Platonic solid).
- The five Platonic solids—tetrahedron, cube, octahedron, dodecahedron, and icosahedron—are all regular solid figures.
"Composite solid figure": A three-dimensional shape formed by combining two or more simple solid figures.
- To find the total volume, we broke the complex structure down into its constituent composite solid figures.
Variants and Related Words

- Three-dimensional shape (n): A direct synonym phrase.
- Polyhedron (n): A specific type of solid figure with flat polygonal faces, straight edges, and sharp corners or vertices.
- Geometric solid (n): Another common term for a solid figure.
