These Class 4 Maths Chapter 1 question answers provide simple explanations for the chapter and help students revise important concepts. A worksheet-style practice section with answers is also included for students who want to test their understanding.
Class 4 Maths Chapter 1 Shapes Around Us focuses on observing objects and understanding their shapes and parts. For Curious Jr. students, the chapter helps them learn about objects such as bricks, boxes, balls, buildings, and other things they see around them.
The chapter also introduces ideas such as:
Faces, edges, and corners
Flat and curved surfaces
Different views of objects
Floor maps and deep drawings
Patterns and symmetry
Shapes in everyday objects
1. How many faces does a brick have?
Answer: A brick has 6 faces.
2. How many corners does a brick have?
Answer: A brick has 8 corners.
3. What are the parts where two faces of a solid object meet called?
Answer: They are called edges.
4. What are the points where edges meet called?
Answer: They are called corners or vertices.
5. Which object has a curved surface: a ball or a brick?
Answer: A ball has a curved surface.

1. A ball is an example of which type of solid shape?
Answer: A ball is an example of a sphere.
2. A brick is similar to which solid shape?
Answer: A brick is similar to a cuboid.
3. Which object can roll easily: a ball or a brick?
Answer: A ball can roll easily because it has a curved surface.
4. Which object has flat rectangular faces: a brick or a ball?
Answer: A brick has flat rectangular faces.
5. Name two objects around you that have shapes similar to a cuboid.
Answer: A book and a pencil box are examples.
A solid object can have different parts that help us describe its shape.
A face is a flat surface of a solid object.
An edge is where two faces meet.
A corner is where edges meet.
For example, a brick has 6 faces, 12 edges, and 8 corners.
Objects can have flat surfaces, curved surfaces, or both.
A brick has flat surfaces, while a ball has a curved surface. A cylinder has both flat and curved surfaces.
1. How many faces does a cuboid have?
Answer: 6 faces
2. How many edges does a cuboid have?
Answer: 12 edges
3. How many corners does a cuboid have?
Answer: 8 corners
4. Does a sphere have flat faces?
Answer: No. A sphere has a curved surface.
5. Name one object with a curved surface.
Answer: A ball.

Answer: A brick has six faces. A brick is similar to a cuboid, which has six flat faces.
Answer: A brick has 12 edges and 8 corners. The edges are formed where two faces meet, while the corners are points where edges meet.
Answer: A deep drawing is a drawing that represents a solid object in a way that shows its different dimensions, such as length, breadth, and height. It helps us understand a three-dimensional object on a flat page.
Answer: No. From one particular viewpoint, we cannot normally see all six faces of a brick at the same time. A drawing may show some of its faces to represent its three-dimensional form.
Answer: Rectangular bricks can be placed closely together and stacked to form walls. Their flat faces make them suitable for building structures.
A brick is a useful example for understanding solid shapes. It has:
6 faces
12 edges
8 corners
The faces of a brick are flat. When a brick is drawn on paper, the drawing represents its three-dimensional shape.
When drawing a brick, we cannot normally show all its faces from a single viewpoint. A three-dimensional drawing shows some faces together to give an idea of the object's length, breadth, and height.
Students can observe a matchbox, book, or pencil box and try to draw it from different viewpoints.
A floor map shows the arrangement of spaces from above. It can help us understand where different parts of a building or room are located.
A floor map is different from a drawing that shows the object or building from the outside.
A deep drawing represents a three-dimensional object. It gives an idea of dimensions such as length, breadth, and height.
For example, a drawing of a house can show its different parts in a way that gives the impression of depth.

Shapes and objects can be arranged to create different patterns. Some patterns may have symmetry, which means one part can correspond to another part when divided along a suitable line.
Students can look for patterns in floor designs, walls, objects, and pictures around them. Drawing and completing simple patterns can help them understand symmetry and shapes.
Answer: A face is a flat surface of a solid object.
Answer: An edge is the line or boundary where two faces meet.
Answer: A corner is a point where edges meet.
Answer: A book and a pencil box are examples.
Answer: A ball is an example of an object with a curved surface.
