To solve this problem, we need to determine how much paint is required for the area to be covered and then compare the prices of different tin sizes to find the cheapest option.

### Step 1: Calculate the area to be covered

Given that 1.5 liters of paint is needed for two coats, we can find out how much area this will cover.

From the problem, we know:
- 5 liters of paint covers $$6 \, \mathrm{m}^2$$.

First, we need to find out how much area 1 liter of paint covers:
$$
\text{Area covered by 1 liter} = \frac{6 \, \mathrm{m}^2}{5 \, \mathrm{liters}} = 1.2 \, \mathrm{m}^2/\mathrm{liter}
$$

Now, we can find out how much area 1.5 liters of paint will cover:
$$
\text{Area covered by 1.5 liters} = 1.5 \, \mathrm{liters} \times 1.2 \, \mathrm{m}^2/\mathrm{liter} = 1.8 \, \mathrm{m}^2
$$

### Step 2: Determine the total amount of paint needed

Since we need two coats, the total amount of paint required will be:
$$
\text{Total paint needed} = 1.5 \, \mathrm{liters} \times 2 = 3 \, \mathrm{liters}
$$

### Step 3: Compare prices of paint tins

Next, we need to find the prices of 20-liter and 5-liter tins from local shops. Since I cannot browse the internet, I will guide you on how to do this:

1. **Search for local paint shops**: Look for advertisements or websites of local hardware stores or paint suppliers.
2. **Check the prices**: Find the price for a 20-liter tin and a 5-liter tin of paint.

### Step 4: Calculate the cost per liter

Once you have the prices, calculate the cost per liter for both sizes:
- For the 20-liter tin:
$$
\text{Cost per liter} = \frac{\text{Price of 20-liter tin}}{20}
$$

- For the 5-liter tin:
$$
\text{Cost per liter} = \frac{\text{Price of 5-liter tin}}{5}
$$

### Step 5: Determine the cheapest option

Compare the cost per liter for both tins and choose the one that is cheaper.

### Conclusion

Once you have the prices and calculated the costs, you can mention the name of the shop where the cheapest tin can be purchased.

Please provide the prices you find, and I can help you with the calculations!
To determine the cheapest paint tin to buy, calculate the cost per liter for both 20-liter and 5-liter tins from local shops. Compare the two and choose the tin with the lower cost per liter. Mention the name of the shop where you find the better deal.
