A cow drinks 56 litre water per day on a 485 litre water that a trough can hold. Would 8 cows have enough water to drink per day?

No, 8 cows would need a total of 448 litres of water per day (56 litres x 8 cows). Since the trough can only hold 485 litres of water, it would not be enough for all 8 cows to have enough water to drink for the day.

Step 1: Calculate the amount of water required by 8 cows per day.

Amount of water required per cow per day = 56 liters
Amount of water required by 8 cows per day = 8 - 56 = 448 liters

Step 2: Check if the water trough has enough capacity for 8 cows.

Capacity of the water trough = 485 liters
Water required by 8 cows = 448 liters

Step 3: Compare the water required to the water trough capacity.

448 liters < 485 liters

Conclusion:

Yes, 8 cows would have enough water to drink per day from the 485-liter water trough.
