Answer:
The volume of an object is the amount of space it fills.
Large volumes are measured in cubic metres (m3
).
Smaller volumes are measured in cubic centimetres (cm3
) or cubic millimetres (mm3
).
In this cuboid there are 3 layers of cubes.
There are 2 rows of 4 cubes in each layer.
The total number of cubes = 4 × 2 × 3
The volume of the cuboid = 4 × 2 × 3 = 24 cm3
For any cuboid:
Volume = length × width × height
or Volume = area of cross-section × length
The volume of liquids is usually measured in litres or millilitres.
1 litre = 1000 ml and 1 ml = 1 cm3
1 litre = 1000 cm3
and 1 m
3
= 1000 litres
• Suggest dimensions you could use to make a carton with a volume of 1 litre (1000 cm³).
