MEASURES OF VOLUME

1. Measures of volume
   The space occupied by any object is called the volume of that object. Also, the
   measure of the inner space of a hollow solid is called its capacity.

The measure of length of a line segment is in terms of centimeter. The measure of

area of a region or surface in terms of the unit is called the unit square. The volume

of a solid is measured in terms of unit cube. To express the volume of solids, cubic

centimeter or cm^3 is used.

Introduction of the concept of volume must be preceded by a clear explanation about

the difference between area and volume. When the child is able to conceptualize the

difference between the two, the idea of volume may be taught using three dimensional

boxes and cylinders.

To enable the child to have a better understanding of the concept of volume, a bottle

filled with water may be given for exploration. Then the water in the bottle may be

poured to another container and now the child be told that the volume of the bottle

is equal to the volume of water in the container.
