Question

3cm cubed equals...mm cubed
3m cubed equals...cm cubed
9km cubed equals...m cubed

Answer 1

To convert between the different units of volume, you can use the following conversion factors:

1 cm = 10 mm
1 m = 100 cm
1 km = 1000 m

Now, let's perform the conversions:

1. **3 cm³ to mm³**:
\[
3 \, \text{cm}^3 = 3 \, \text{cm}^3 \times (10 \, \text{mm/cm})^3 = 3 \, \text{cm}^3 \times 1000 \, \text{mm}^3/\text{cm}^3 = 3000 \, \text{mm}^3
\]

2. **3 m³ to cm³**:
\[
3 \, \text{m}^3 = 3 \, \text{m}^3 \times (100 \, \text{cm/m})^3 = 3 \, \text{m}^3 \times 1000000 \, \text{cm}^3/\text{m}^3 = 3000000 \, \text{cm}^3
\]

3. **9 km³ to m³**:
\[
9 \, \text{km}^3 = 9 \, \text{km}^3 \times (1000 \, \text{m/km})^3 = 9 \, \text{km}^3 \times 1000000000 \, \text{m}^3/\text{km}^3 = 9000000000 \, \text{m}^3
\]

So the final results are:
- 3 cm³ equals 3000 mm³
- 3 m³ equals 3,000,000 cm³
- 9 km³ equals 9,000,000,000 m³
