Solids have a hard and fast form and occupy a space. A shape is made from polygonal regions referred to as its faces.
A form with the handiest dimensions (duration and width) and no thickness is known as a -dimensional form. Squares, Circles, Triangles, and so on are -dimensional objects. Also regarded as “2D”.
Shapes that may be measured in three instructions are referred to as third-dimensional shapes. These shapes also are referred to as strong shapes. Their dimensions are length, width, and height (or intensity or thickness).
