Answer 1

Let l, b and h be the length, breadth and height of the given cuboid respectively.

∴ Volume = lbh.

(i) Length is doubled = 21

∴ The volume will be the same.

(ii) Length is doubled = 21

breadth is same = b height is doubled = 2h

∴ Volume = 2l x b x 2h = 4 lbh

∴ Volume will be 4 times
