Overview

In our daily lives, we come across many objects like books, balls, glasses, and boxes. These objects have a fixed shape and occupy space. In mathematics, such objects are called solids. Unlike flat shapes such as squares or circles, solids are three-dimensional. This chapter, 'Recognition of Solids'

Key Concepts

Solids are 3D shapes because they

Solids are 3D shapes because they have three dimensions: length, breadth, and height. Examples include a dice (cube), a book (cuboid), a can (cylinder

A face is a flat surface

A face is a flat surface of a solid. An edge is where two faces meet. A vertex (plural: vertices) is a corner point where edges meet. For example, a c

A net is a 2D pattern

A net is a 2D pattern that can be folded to form a 3D solid. For example, a cube can have 11 different nets. Each net has 6 squares arranged in a way

An oblique sketch is a way

An oblique sketch is a way to draw a 3D shape on a 2D surface like paper. It shows the front, side, and top faces to give a realistic view. Hidden edg
