Let's go through the problem in the image.

### Given Information:
- A tin of paint covers **4 m²**.
- You need to cover a **50 m²** wall.

### To Find:
- The number of tins required to cover a **50 m²** wall.

### Solution:
1. **Calculate the total number of tins needed:**
   - The total area to cover is **50 m²**.
   - Each tin covers **4 m²**.
   - To find the number of tins required, divide the total area by the coverage of one tin:
   \[
   \text{Number of tins} = \frac{\text{Total area}}{\text{Area covered by one tin}} = \frac{50}{4} = 12.5
   \]

2. Since you can't purchase half a tin, you'll need to round up to the next whole number.
   - Therefore, you will need **13 tins** to cover the entire wall.

Would you like a more detailed explanation, or do you have any questions?

### Relative Questions:
1. What is the formula to calculate the total cost if each tin costs £12.50?
2. How would the number of tins change if the area of the wall was increased to 75 m²?
3. What would be the total cost of buying 13 tins at £12.50 each?
4. How would the calculation change if each tin covered 5 m² instead of 4 m²?
5. What if you needed a second coat of paint, how many tins would be required in total?

### Tip:
Always round up to the next whole number when dealing with real-world quantities that cannot be fractional, like paint tins.

How many tins of paint are required to cover a 50 m² wall if one tin covers 4 m²?

Learn how to calculate the number of tins required to cover a 50 m² wall, with each tin covering 4 m². The problem involves division and rounding up, making it a practical application of real-world math. Ideal for students in Grades 6-8.
