Answers & Comments
answer : we have to convert 154dmcube into cm cubic form
so we get answer by converting 154dm into cm is 154000 (1dm =1000cm)
now the volume of the cylinder is 154000
vol. of cylinder =πr^2h
154000=22/7×35×35×h
154000=22×5×35×h (by cutting)
154000/22×5×35=h
we get 40 cm
therefore the height is 40cm
