Answer: 90 Newton weight a height of 5 meters.

Explanation: To figure out "work", in physical science, the formulais is force X distance = work.

So if you add the the question about the sofa it would look like this

90 X 5 = 450

and the other question just add it in like this

60 X 30 = 180

You can already tell that 450 is bigger than 180
