Answer by ellie
It is between 248 and 252mm in length.

Answer by Bruce W
Given that the wooden pole is 450mm to the nearest mm, the minimum and maximum measurements respectively would be:-
449.5 to 450.4999…. mm (just written as 450.5mm)

The length of wood removed is 200mm to the nearest mm. Similarly min & max values would be:-
199.5 to 200.5 mm.

Well, what can we say about the remaining section of pole?
The maximum remaining pole length can only be: the maximum possible orginal length MINUS the minimum possible removed length.

So: 450.5 MINUS 199.5 gives 251.0 (maximum remaining length)

and for minimum remaining length: equals the shortest original length MINUS the maximum removed length.
449.5 – 200.5 giving 249.0

We can say that the remaining length lies between 249.0 and 251.0 mm

hope this helps
