Recognition of Solids

In this topic, we will study the difference between a plane figure and a solid figure. It illustrates the shape and number of dimensions of solid figures. We will also learn about cubes, cuboids, prisms, pyramids, spheres and cones.

Via this topic, we will learn the definitions of face, edge and vertex of a solid figure. These are the elements of a solid figure. It also explains Euler's formula and its application for the solid shapes.

From this topic, we will learn the nets of 3D solids. It includes the activity to make a pattern of a solid shape called nets. It also briefs the procedure to make the nets of cube, cuboid, cylinder and cone.
