Visualising solid shapes is a very useful skill. We can see the hidden parts of a solid shape. For example, when a cuboid with a square face is cut vertically, then each face is a square. The face is a cross section of the cuboid

Platonic solids are 3D shapes formed using only regular shapes. Only 1 type of regular shape is used to make a platonic solid. Platonic solids are the simplest and purest form of 3D shapes.
Shapes which can be measured in 3 directions are called three-dimensional shapes. These shapes are also called solids. Length, width, and height (or depth or thickness) are the three measurements of the three-dimensional shapes. These are the part of three-dimensional geometry.

Three dimensional shapes are shapes with height, width, and depth. In contrast, two dimensional shapes only have height and width, or length and width.
4D shapes are shapes in four dimensional space. Since we live in 3D space it is very difficult for most people to visualise 4D shapes.
