NCERT Solutions Chapter 15:  VISUALISING SOLID SHAPES

 In this chapter, you will classify figures you have seen in terms of what is known as dimension. In our day to day life, we see several objects like books, balls, ice-cream cones etc., around as which have different shapes. One thing common about most of these objects is that they all have some length, breadth and height or depth.That is, they all occupy space and have three dimensions. Hence, they are called three dimensional shapes. Do you remember some of the three dimensional shapes(i.e.,solid shapes)  we have seen in earlier classes?
