I see the photo you uploaded contains a set of physics and math exercises in Swedish, involving unit conversions, prefixes, and measurements. Let's work through some of the problems:

### Problem 1301: **Skriv i meter.**
Convert the following into meters:
- a) 42.4 km = \( 42.4 \times 10^3 \) m = 42,400 m
- b) 20 cm = \( 20 \times 10^{-2} \) m = 0.2 m
- c) 7 mm = \( 7 \times 10^{-3} \) m = 0.007 m

### Problem 1302: **Skriv i dm².**
Convert the following areas into square decimeters (dm²):
- a) 2 m² = \( 2 \times 100 \) dm² = 200 dm²
- b) 300 cm² = \( 300 \div 100 \) dm² = 3 dm²
- c) 50 mm² = \( 50 \times 10^{-2} \div 100 \) dm² = 0.005 dm²

### Problem 1303: **Skriv i dm³.**
Convert the following volumes into cubic decimeters (dm³):
- a) 0.5 m³ = \( 0.5 \times 1000 \) dm³ = 500 dm³
- b) 7,500 cm³ = \( 7,500 \div 1000 \) dm³ = 7.5 dm³
- c) 5.6 liter = 5.6 dm³ (since 1 liter = 1 dm³)

Here are 5 related questions to test your understanding:
1. How would you convert 15 kilometers into millimeters?
2. Convert 12,000 square centimeters into square meters.
3. How many cubic centimeters are in 0.75 cubic meters?
4. What is the conversion factor between cubic decimeters and liters?
5. If an area is 4 hectares, how many square meters is this?

### Tip: 
Always remember to use the correct conversion factor when switching between units of different magnitudes (e.g., milli-, centi-, kilo-).

Convert various units and measurements as provided in the image, focusing on metric units such as meters, square meters, and cubic meters, along with prefixes like kilo-, centi-, and milli-.
