A cube with sides of length 1 metre has a volume
of 1 .
(read one cubic metre). |
| The same cube measured in decimetres:
|
 (read one thousand cubic decimetres) |
| The same cube measured in centimetres:
|
(read one million cubic centimetres) |
We see

Examples:
How many
are 10.5
?

|
| 1 0 | 5 0 0 | 0 0 0 |
Answer: 10 500 000
Example:
How many litres are 5 ?
We know that
1 litre =
1
so begin by converting
into .

|
|
|
|
| 5 | 0 0 0 |
Answer: 5000
= 5000 litres
Example:
How many are 500 cl
(centilitres)?
| kl | hl | dal | l | dl | cl | ml |
| 5 | 0 | 0 |
500cl = 5 liters
5 liters = 5

| 0 | 0 0 5 |
Answer: 500cl =
0.005
