  1. 13.1 Introduction. From Class IX, you are familiar with some of the solids like cuboid, cone, cylinder, and sphere (see Fig. 13.1). You have also learnt how to find their surface areas and volumes. Fig. 13.1. In our day-to-day life, we come across a number of solids made up of combinations of two or more of the basic solids as shown above.

    • 13.6 Volume of a Cuboid
    • Volume of a Cuboid = base area × height = length × breadth × height

    Wherever we look, usually we see solids. So far, in all our study, we have been dealing with figures that can be easily drawn on our notebooks or blackboards. These are called plane figures. We have understood what rectangles, squares and circles are, what we mean by their perimeters and areas, and how we can find them. We have learnt these in earl...

    You have already learnt about volumes of certain figures (objects) in earlier classes. Recall that solid objects occupy space. The measure of this occupied space is called the Volume of the object. Note : If an object is solid, then the space occupied by such an object is measured, and is termed the Volume of the object. On the other hand, if the o...

    or l × b × h, where l, b and h are respectively the length, breadth and height of the cuboid. Note : When we measure the magnitude of the region of a space, that is, the space occupied by a solid, we do so by counting the number of cubes of edge of unit length that can fit into it exactly. Therefore, the unit of measurement of volume is cubic unit....
