What this chapter teaches.
Building on the cube, cuboid, sphere, cylinder, and cone from Class 2, children now look more closely at each shape’s properties: how many flat faces it has, how many edges (where two faces meet), and how many corners (vertices). For example, a cube has 6 flat faces, 12 edges, and 8 corners, while a sphere has no flat faces, edges, or corners at all.

Activity 1 — Sorting Toys by Shape.
Children sort a set of toys (blocks, balls, boxes, cones) by which 3D shape they match, revising the shape names from Class 2.

Activity 2 — Counting Faces.
For each toy/shape, children count the number of flat surfaces (faces) it has — for example, a cuboid-shaped box has 6 faces.

Activity 3 — Counting Edges and Corners.
Children count the edges (straight lines where two faces meet) and corners (points where edges meet) of shapes like cubes and cuboids.

Activity 4 — Which Shapes Stack?.
Children test which toys stack well on top of each other (shapes with flat faces, like cubes and cuboids) and which do not (shapes with curved surfaces, like spheres and cones).

Why This Chapter Matters

Counting faces, edges, and corners is the next level of detail in understanding 3D shapes, beyond just naming them — this careful, structured way of describing shapes is used throughout geometry in later classes.

How to Use These Solutions

Work through the activities above together with the child’s own textbook pictures where relevant, talking out loud through each idea. You can download the full chapter from our Class 3 Maths NCERT book page, or browse every Class 3 subject on our Class 3 hub.

Frequently Asked Questions

How many faces, edges, and corners does a cube have?
A cube has 6 faces, 12 edges, and 8 corners.

Why does a sphere have no edges or corners?
Because a sphere’s entire surface is one continuous curve, with no flat faces meeting to form an edge or a corner.
