The rule when rounding off numbers is "If the first figure to be discarded is 5 or more then the previous figure is increased by 1".

The first figure to be discarded is '6' and as this is greater than 5 then the previous figure (4) is increased by 1 (to 5).

29.46 when rounded off to three significant figures is 29.5.
