Answer 1

Answer:

1. m² = m x m

= 100 cm x 100 cm

= 10000cm²

2. litres and mili litres

3. m³=m x m x m= 100cm x 100 cm x 100 cm= 1000000cm³= 10⁶cm³

4. 7²= 49 cm²

5. 25 cm= 0.25 m 15 cm = 0.15m 2cm= 0.02 m

0.25×0.15×0.02=0.000075m³

Answer 2

Answer:

The base unit of volume in the SI system is the cubic meter. There are 1000 liters per cubic meter, or 1 liter contains the same volume as a cube with sides of length 10cm. A cube with sides of length of 1 cm or 1 cm3 contains a volume of 1 milliliter. A liter contains the same volume as 1000 ml or 1000 cm3.
