NCERT Solutions for Class 7 Maths Chapter 15 Visualising Solid Shapes: In our daily life, we come across many objects. If we take a plain sheet of paper it is in the shape of a rectangle and it has two dimensions. We can measure the length and breadth of paper and we can find the area and perimeter of paper, which we have studied in the previous chapters of NCERT Solutions for Class 7 Maths. We have come across shapes like triangle, circle and parallelograms in NCERT Solutions for Class 7, these are plane figures. A cricket ball, a book, an ice cream cone, a pipe, etc are solid figures and are three dimensional. If we take a book we can say it is in the shape of a cuboid and we can measure length, breadth, and height also and using this quantity we will find the volume or capacity of solids, which we will study in NCERT Solutions of coming class. Here in NCERT Solutions for Class 7 Maths Chapter 15 we will discuss certain solid shapes and how to visualize it.
We have seen dice which are solid in shape. This shape is known as a cube. A cube has equal length, breadth, and height. It consists of 6 faces, 12 edges and 8 vertices as shown in the figure below.
A ball is in the shape of a sphere. A watercarrying pipe is in the shape of a cylinder. The shadow of a sphere will be circular in shape, the shadow of a cone will be triangular in shape, the shadow of the cylinder will be rectangular in shape. The horizontal crosssection of the cylinder is rectangular in shape and vertical crossection is circular in shape as shown in the figure below. Can you find out horizontal and vertical crossection of sphere, cube, and cone also?
