The definition an oblique cylinder has the same volume as a right cylinder of the same base and height. So the Volume of Cylinder B doesn't depend on the "lean" and is the same as Cylinder 'A'; 360 cu.cm.
we are finding area which is squared, or we can put it in an equation, (0.5*20)*(0.25*20) or 0.5*0.25*20^2 which equals 50 but (0.5*0.25)*20 only equals 2.5 therefor he is incorrect and the correct answer would be 20^2 or 400 times the area.
