Identification and Naming of Solids
Solid figures are often called 3-dimensional shapes or 3D shapes. A solid figure is simply anything that occupies space and also has a definite shape. Most solids, or 3D shapes, such as stones and trees, have rough and irregular shapes. However, some solids, such as boxes, tins, football, etc. have regular shapes. These are often called geometrical solids.
