let d be the diameter and h be the height of the first cylinder
then 2d will be the diameter and 1/2 h will be the height of the second cylinder
volume of 1st cylinder= phi/4 d^2 h
volume of 2nd cylinder= phi/4 (2d)^2 (1/2h)= 1/2 phi (d)^2 h
1/4:1/2
the weight is 60 kg

30 kg.
If l,b & h corresponds to length,breadth & thickness respectively
As l*b*h=30 & (l/2)*b*(2h)=l*b*h will be equal to 30
