NCERT Solutions for Class 7 Maths Chapter 15 Visualising Solid Shapes (EX 15.1) Exercise 15.1
The mathematical study of spatial relationships is known as Geometry. In our everyday lives, it also aids in calculating heights and distances, from calculating a box’s volume to determining a room’s measurements. Students must therefore master the ideas surrounding solid shape visualisation.
As all shapes and things in the human world have length, breadth, and height, therefore, Geometry is the study of these items in two and three dimensions. The NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1 Understanding terminology like 2D and 3D and the significance of their respective fields is the first step towards visualising solid shapes. Diagrams describe concepts such as vertices, edges, and faces.
Students must be aware of the distinction between solid and flat geometry. The study of lines and shapes like squares, triangles, rectangles, and hexagons is known as “Plane Geometry,” also called “TwoDimensional Geometry.” In contrast, the study of prisms, cylinders, cubes, pyramids, spheres, and other threedimensional objects is known as “Solid Geometry.”The NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1 are the best materials to understand the chapter deeply.

Students can learn about threedimensional space and how objects can be formed in three dimensions by completing some of the activities in the NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1. They are instructed to create the appropriate frames or nets for the shapes and then prompted to try to construct the shapes using the prepared cutouts or frames. As a result, it will be easier to develop the visualisation abilities needed for the exercise and the NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1.
The NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1 begin with an introduction to forms and objects in 2D and 3D space. In NCERT Solutions Class 7 Maths Chapter 15 Exercise 15.1, the meanings of terminology like edges, faces, and vertices of shapes are revised. Along with the idea of perceiving solid objects and how to observe their distinct sections, further solid drawings on a flat surface, oblique sketches, and isometric sketches are explained. The chapter’s last section discusses Shadow Play as a technique to view threedimensional objects in a twodimensional environment.

\begin{array}{l}\text{(vi) The given net can be folded as:}\end{array} \text{}
\text{Thus, a cube can thus be formed in above way}\text{.}
Q.2
$\begin{array}{l}\text{Dice are cubes with dots on each face. Opposite faces of}\\ \text{a die always have a total of seven dots on them.}\end{array}$
$\begin{array}{l}\text{Here are two nets to make dice}\left(\text{cubes}\right)\text{; the numbers}\\ \text{inserted in each square indicate the number of dots in}\\ \text{that box.}\end{array}$
