The answer to this question is: Invention
The romans civilization was known as the civilization that made the most inventions during that period.
One of their famous inventions is the development of wheels, that allow us to carry several objects that weigh several times heavier compared to our body weight.
This is what i got
Only 2 of the 25cm cake will fit in a 600mm x 500mm
600mm=60cm
500mm=50cm
60 divided by 25 : 2.4
50 divided by 25 : 2
so the best it could fit is 2 of the 25cm cakes
Trade is when two or more people exchange items such as food , money , books and etc...
When our country = America ( USA ) trades goods such as money , or food and medical supplies to other countries ( Nations ) to help them and in return we might get more supporters or better Technology.
I really hope that this helps you out a lot.
