5.0.0. MEASUREMENT OF VOLUMES OF OBJECTS:
Objects have different shapes. As a result, volumes of some objects can be determined or calculated using formula while volumes of some other objects can not be calculated using formulae. Let us look into the types of objects that we have and how their volumes can be calculated thus:
5.1.0. Regular Objects:
These are objects that have definite shapes. The volumes of these types of objects can be calculated or determined by the use of appropriate formulae.
For example, volumes of object such as box, sphere, cylinder, cone, etc can be calculated using appropriate formula.
5.2.0. Irregular Object:
These are objects that do not have definite shapes. Volumes of these types of objects can not be calculated by the use of formulae. Their volumes can only be calculated or determined by the following steps:
Step I: tie the object to one end of a rope
Step II: fill an over flow can or eureka with water
Step III: immerse the object into the water in the over flow can.
You will observed that the level of water in the can will rise up and overflow. Collect the water that overflow into a container. This water that overflow is called liquid displaced.
Step IV: use a measuring cylinder and measure the volume of the liquid displaced.
Step V: The volume of the liquid displaced is the volume of the object.
