- What is a form?
- Do you remember what a geometric shape is? Name me some.
FORM and VOLUME___________________________________________________________
Form is an element of art. At its most basic, a form is a three-dimensional geometrical figure (i.e.: sphere, cube, cylinder, cone, etc.), as opposed to a shape, which is two-dimensional, or flat.
A form always has three dimensions; length, width and height. When you stand next to an object you can go round it and see the three dimensions.
Volume (three-dimensionality) can be simulated in a two-dimensional work (like a drawing) thanks to the use of light and shadows, perspective, etc.
Solids are three dimensional rigid bodies that occupy some volume or capacity. Solids have length, width and height.
Type of Solids:
- Polyhedron: regular and others.
- Non Polyhedron
1. Polyhedron is a geometric solid in three dimensions with flat faces and straight edges. Each surface is a polygon.
2. Non Polyhedron: solids like cylinder, cone, and sphere have surfaces which are curved or combination of both curved and flat surfaces.
Name shapes and find out its equivalent volume, for example: a triangle would be a pyramid or a tetrahedron. What is the difference? (Regular or other polyhedrons)
A net of a polyhedron is an arrangement of edge-joined polygons in the plane which can be folded (along edges) to become the faces of the polyhedron. Polyhedral nets are a useful aid to the study of polyhedra and solid geometry in general, as they allow for models of polyhedra to be constructed from material such as thin cardboard.
Sculpture is three-dimensional artwork created by shaping or combining hard materials.

- Look around you at different objects. Focus on only the light and dark areas and not the actual colours. Concentrate on the light and shadows. Then partly close your eyes until you see the values of that object.
- Make your own Polyhedron in a coloured cardboard. Check this page: Solid shapes and their nets.
