The students should determine the volume of 3 solid bodies. In
doing this they should know that the cubic meter (m3) is
the unit of volume and also that the term liter (l) is very
- On immersion of a solid body in a graduated cylinder, the
difference of the initial and final water levels gives the volume
directly. The accuracy of this method increases with increasing
narrowness of the graduated cylinder, i.e. with increasing
difference in the water levels.
- Immersion of a body in an overflow vessel and weighing the mass
of the overflow volume generally results in more accurate results,
since it is possible to read the scales more accurately than the
graduated cylinder (meniscus!).
- For regular bodies the calculation of the volume from the
length, width and height, which have been measured with a vernier
caliper, is the most accurate measuring method.
