What will happen to the volume of a cuboid if its :
(i) Length is doubled, height is same and breadth is halved?
(ii) Length is doubled, height is doubled and breadth is same?
(i) Let ,
Length of cuboid = l
Breadth = b
Height = h
Volume of cuboid = lbh
Now,
Case(i)
Length become = 2l
Height = h
Breadth = 
Volume of cuboid = 
(ii)
Case(ii)
Length become = 2l
Breadth = b
Height = 2h
Volume of cuboid =
