Sub-topic 11.4 : - Relation between volume and capacity
Introduction:
The volume of a three-dimensional shape is a measurement of the space occupied by the
shape.
In daily life, the term volume refers to solid objects and the term capacity refers to liquids
or gases.
Volume is measured in cubic units.
The volume of a unit cube
= 1 unit × 1 unit × 1 unit
= 1 unit (Read as one cubic unit)
3
The volume of a cube with sides 1 cm × 1 cm × 1 cm
3
Volume = 1 cm × 1 cm × 1 cm = 1 cm (Read as one cubic cm)
3
1 cm occupies the same amount of space as 1 millilitre.
If we fill water in 1 cm cube and measure it. We can see that it contains 1 ml of water.
3
Hence, we can say that 1 cm = 1 ml
Some important units of conversion for volume are:
3
1 cm = 1ml
10 cm = 10 ml
3
100 cm = 100 ml
3

3
1000 cm = 1000 ml which is same as 1000 cm = 1 litre.
3
Example 1: What is the capacity of the bottle if the volume is 2345 cm ?
Solution:
3
The capacity of the bottle is 2345 ml = 2 litres 345 ml as 1cm = 1 ml.
