we know volume of rectangular solid - length * breadth * height

therefore for quantity of A = 20x

For quantity B = 80y


But we donot know the value of x and y and therefore we cannot determine which one would be greater

since if x=1 and y=1 then QTY B is greater

if x=5 and y=1 then QTY A is greater

OPtion is D
