The apothem of a regular polygon is the distance from the centre of the polygon to one its sides.
I will assume that by "square candle" you mean its base is a square.
If its apothem is 5 then its side is 10.
So the fact that the side is given as 10 confirms that and is actually redundant information.
Volume = 10cm x 10cm x 9cm = 900 cm^3
