12 Visualising Solid Shapes

Learning Objectives

After studying this chapter, students will be able to... Scan to learn
 identify and count vertices, edges, and faces of different solid shapes
 recognise different nets of 3D shapes
 draw 3D solids on a flat surface by oblique sketch and isometric sketch
 view different sections of solids by cutting, slicing, or by using shadow play, or by looking at different angles

GET READY!

Avik and Avika visit a toy factory to see how they make toys using scrap plastic waste.

These blocks are in the
form of basic solid shapes
Hey! Avika, look at here, like cubes, cuboids, cones,
these blocks are made by cylinders, and many other
waste plastic material. shapes.

How can we identify
Can you identify the and count the
edges, vertices and edges, vertices and
faces of these blocks? faces of a solid
shape?
