A family requires 2.2 L of milk every day. Find the total quantity of milk required in a mouth of 31 days.

Answer

To find the total quantity of milk required in a month of 31 days, we can follow these steps:

### Step 1: Identify the daily requirement of milk
The family requires 2.2 liters of milk every day.

### Step 2: Determine the number of days in the month
We know that the month has 31 days.

### Step 3: Calculate the total quantity of milk for 31 days
To find out the total quantity of milk required for 31 days, we will multiply the daily requirement by the number of days in the month.

\[ \text{Total milk required} = \text{Daily requirement} \times \text{Number of days} \]

Substituting the values we have:

\[ \text{Total milk required} = 2.2 \, \text{liters/day} \times 31 \, \text{days} \]

### Step 4: Perform the multiplication
Now, let's calculate:

\[ 2.2 \times 31 \]

Breaking it down:
- First, multiply 2.2 by 31:

\[ 2.2 \times 31 = 68.2 \]

### Step 5: Write the final answer
Thus, the total quantity of milk required in a month of 31 days is:

\[ \text{Total milk required} = 68.2 \, \text{liters} \]

### Final Answer:
The family requires **68.2 liters** of milk in a month of 31 days.
