### Topics from which case study questions may be asked

- Plane figures and solid shapes
- Faces, edges and vertices of solid shapes
- Nets for building 3-D shapes
- Drawing solids on a flat surface
- Visualising different section of a solid

Plane figures are of two-dimensions and solid figures are of three-dimensions. In a solid figure, the corners are the vertices, the line segments are its edges and its flat surface are its faces.

A net is an arrangement of plane figures connected at their edges, lying in the same plane, that can be folded to make a three-dimensional solid.

Figures drawn on paper are called plane figure. Solid figures are those figures which occupy space.

Case study questions from the above given topic may be asked.

Plane figures are 2-dimensional, while solids are 3-dimensional.

Visualising solid shapes is a very useful skill. You should be able to see â€˜hiddenâ€™ parts of the solid shape.

### Frequently Asked Questions (FAQs) on Visualizing Solid Shapes Case Study

#### Q1: What are solid shapes?

A1: Solid shapes are three-dimensional figures that have length, breadth, and height. Common examples of solid shapes include cubes, cuboids, cones, and cylinders. Unlike two-dimensional shapes, these objects occupy space and can be viewed from different perspectives.

#### Q2: What is the difference between 2D and 3D shapes?

A2: 2D shapes have only two dimensionsâ€”length and breadthâ€”and can be drawn on flat surfaces, like squares or circles. In contrast, 3D shapes have three dimensionsâ€”length, breadth, and heightâ€”like cubes or spheres. While 2D shapes can be represented easily on paper, 3D shapes are visualized as solid objects that occupy space.

#### Q3: What are oblique and isometric sketches?

A3: An **oblique sketch** is a simple way to represent a 3D object on a 2D plane. It gives a distorted view because one side is drawn at an angle. An **isometric sketch**, on the other hand, provides a more accurate representation of a solid object, with all dimensions to scale, giving a clearer idea of how the object looks from different angles

#### Q4: How can we visualize cross-sections of solids?

A4: Cross-sections are the shapes you get when you slice a solid object along a plane. For example, cutting a cylinder horizontally would give a circular cross-section, while cutting a cube horizontally or vertically would give a square cross-section.

#### Q5: How are shadows of 3D objects formed?

A5: Shadows of 3D objects depend on the shape of the object and the angle of light. For example, a cube can cast a square or rectangular shadow, while a cylinder can cast a circular or rectangular shadow based on how light falls on it. Visualizing shadows helps in understanding how 3D objects interact with lightâ€‹.

#### Q6: **What are polyhedrons?**

A6: Polyhedrons are three-dimensional shapes with flat faces. Each face is a polygon, and the edges of the polygons meet at vertices. Common examples of polyhedrons include cubes (with square faces) and pyramids (with triangular faces). A polyhedron is named based on the shape and number of its faces.

#### Q7: **How do you calculate the number of faces, edges, and vertices of a solid shape?**

A7: For polyhedrons, the relationship between the number of faces (F), edges (E), and vertices (V) is given by Euler’s formula:

V âˆ’ E + F = 2

This formula helps in identifying the structure of a polyhedron. For example, a cube has 8 vertices, 12 edges, and 6 faces, satisfying Euler’s formula.

#### Q10: **Are there any online resources or tools available for practicing **Visualizing Solid Shapes **case study questions?**

A10: We provide case study questions for CBSE Class 7 Maths on ourÂ website. Students can visit the website and practice sufficient case study questions and prepare for their exams. If you need more case study questions, then you can visitÂ Physics GurukulÂ website. they are having a large collection of case study questions for all classes.
