RD Sharma Solutions for Class 7 Maths Chapter 19 Visualising Solid Shapes
Mathematics is not just about numbers and formulas. It also helps us understand the world around us by looking at different shapes and figures. In Class 7 Maths, Chapter 19 of the RD Sharma textbook – Visualising Solid Shapes – takes students into the exciting world of 3D geometry. This chapter helps learners move from studying flat, 2D shapes to exploring solid, 3D shapes that we see and use every day. From boxes and ice-cream cones to footballs and pyramids, everything has a shape and structure. This chapter helps students understand those forms better by learning how to see and draw them.
The RD Sharma Solutions for this chapter offer clear, step-by-step answers to every question in the textbook. These solutions are written in a simple and easy-to-understand language, making it easier for Class 7 students to follow the concepts without getting confused. Each solution explains how to look at solid shapes from different angles, how to draw them using nets, and how to count faces, edges, and vertices. These are important concepts that help build a strong foundation for future math topics like geometry, surface area, and volume.

Access Answers to RD Sharma Solutions for Class 7 Maths Chapter 19 Visualising Solid Shapes
Q1. What is the difference between a 2D shape and a 3D shape?
Answer: A 2D shape has only length and breadth (like a square or circle), whereas a 3D shape has length, breadth, and height or depth (like a cube or sphere).
Q2. Name any three 3D shapes and their number of faces.
Answer: Cube – 6 faces, Cuboid – 6 faces, Cylinder – 3 faces (2 circular and 1 curved).
Q3. How many vertices does a pyramid with a square base have?
Answer: A square pyramid has 5 vertices (4 at the base and 1 at the top).
Q4. How many edges are there in a cube?
Answer: A cube has 12 edges.
Q5. What is a net of a solid shape?
Answer: A net is a two-dimensional pattern that can be folded to make a 3D shape.
Q6. How many faces, edges, and vertices does a cuboid have?
Answer: A cuboid has 6 faces, 12 edges, and 8 vertices.
Q7. Can a solid have a curved surface? Give an example.
Answer: Yes, a solid can have a curved surface. Example: A sphere has only a curved surface and no flat face.
Q8. Which 3D object has only one vertex?
Answer: A cone has only one vertex (the pointed top).
Q9. What is the shape of the base of a cylinder?
Answer: The base of a cylinder is circular in shape.
10. Question: Name a solid shape which can roll and slide both.
Answer: A cylinder can both roll (on its curved surface) and slide (on its flat circular face).
