Solid shapes are three-dimensional (3D) geometric shapes that occupy space and have length, breadth, and height. They are also known as 3D shapes or solids. Unlike two-dimensional shapes like squares or circles, which are flat, solid shapes extend in three directions and possess depth, giving them a form we can hold, touch, and explore in reality. Solid shapes are classified into various categories based on their dimensions. Some of them have curved surfaces, while some are in the shape of pyramids or prisms. Examples of solid shapes include cubes, cuboids, cones, cylinders, spheres, pyramids, and prisms.

The study of 3-dimensional objects, their volume, surface area, and properties is called solid geometry. Solid shapes have faces, edges, and vertices. Understanding solid shapes can be thrilling, akin to being an explorer discovering new lands. When we study these shapes, we look at their attributes, such as their faces, edges, and vertices. Every different solid shape has its unique properties, much like every country has its own unique culture and landscape. Learning about solid shapes will help us in our day-to-day life as most of our activities revolve around and depend on them.
