A children’s home was supplied with 40 cartons of milk. Each carton contained 60 two-hundred millilitre packets of milk. How many litres of milk were supplied?

40 * 60 * .200 = ? L

The 60 two-hundred milliliter packets of milk amount to 60 * 200 = 12000 milliliters of milk, which is 12 liters. This is the amount of milk per carton. The total amount of milk, therefore, is 40 * 12 = 480 liters.

40cartons * 60packets/carton = 2400 packets.

2400packets * 0.2Liters/packet = 480 Liters.

To find the total amount of milk supplied, we need to multiply the number of cartons by the number of packets in each carton and the volume of each packet.

First, let's start with the number of cartons: 40 cartons.

Then, let's move on to the number of packets in each carton: 60 packets per carton.

Finally, we need to know the volume of each packet: 200 milliliters.

To calculate the total amount of milk supplied:
Total milk = Number of cartons × Number of packets per carton × Volume per packet

Substituting the given values:
Total milk = 40 cartons × 60 packets per carton × 200 milliliters per packet

To convert milliliters to liters, we divide by 1000 since there are 1000 milliliters in a liter:
Total milk = (40 × 60 × 200) / 1000 liters

Now, let's solve this equation:
Total milk = (48000) / 1000
Total milk = 48 liters

Therefore, the children's home was supplied with 48 liters of milk.
