A 100 kg log of wood was neatly cut into two smaller pieces. What is the total mass of all the smaller pieces put together?

50 kg

100 kg

200 kg

1,000 kg

Explain.

I would say that the two pieces, which were derived from the 100 kg log, would still constitute almost 100kg except for a minor amount of sawdust used to cut them in half. So the result is that a 100kg log cut into two pieces will still weigh with the two pieces together, 100kg.

Peter is correct!
