The word polyhedra are the plural of the word polyhedron. Polyhedron – A solid shape bounded by polygons is called a polyhedron. So, here we have to define the 3D shapes are: But, before we look at the different solid shapes, we need to understand some common terms that are used to define different dimensions of solid shapes. Let us understand some of these shapes in detail.

For example, the laptop, our rooms, mobile phones, ice cream, tennis balls etc. In our everyday lives, we come across many solid shapes. 3D Shapesģ Dimensional shapes or 3D shapes are the shapes that have all the three dimensions, i.e. Why do we call them 3-dimensional? To understand this, we first need to understand what we mean by the word 3-dimensional shapes. These solid shapes are known as 3-dimensional shapes. Solid occur in different shapes and sizes.A solid occupies a fixed amount of space.An object that has a fixed shape and size is called a solid. The definition of a solid is no different from what we learn in science. So, what are solids in mathematics? Let us find out Solid We read about solids, liquids and gases in science. The things we are talking about such as the room, the bowl, the box are all solid in shape. For example, a park has space for us to play.

When we look at something empty, like a box, room or bowl, even though it seems empty, it still has space.
