Make a conjecture about how many ants might be on the farm. If you added all these ants into the previous question, how would that affect your answer for the total mass of all the animals?

Which is greater, the number of bacteria, or the number of all the other animals in the table put together?

Answer 1

The total mass of the living things on the farm is 588 kg.

Mass calculation

Since on a farm there was a cow, 2 sheep and 3 chickens, to determine what is the total mass of the 1 cow, the 2 sheep, the 3 chickens, and the 1 farmer on the farm, the following calculation must be performed :

• (6.2 x 10) + (4 x 10 x 10) + (2 x 6 x 10) + (3 x 2 x 1) = X
• 62 + 400 + 120 + 6 = X
• 588 = X

Therefore, the total mass of the living things on the farm is 588 kg.
