ANSWER:-------
given :-
length of the rectangular roof = 28m
breadth of the rectangular roof = 12m
we have to find the volume of water if it received 20mm of water.
so first of all, we have to convert 20mm in meters.
20mm = 2cm = 0.02m (height)
therefore volume of the water fell in the roof = l × b × h
= 28 × 12 × 0.02
= 6.72m³
hence, the volume of water fell in the roof is 6.72m³
