1liter = 10 desiliter
2 desiliter = 0.2 liter
1dm^3 = 1 liter
0.2 liter = 0.2 dm^3
1dm = 10cm
7cm = 0.7dm
a)
V = G*h --> h = V/G = (0.2dm^3) / (0.7dm*0.7dm) = 0.41dm = 4.1cm
b)
h = V/G = (0.3dm^3) / (0.7dm*0.7dm) = 0.61dm = 6.1 cm
c)
1 liter = 1000milliliter
h = V/G = (0.5dm^3 / (0.7dm*0.7dm) = 1.02dm = 10.02cm
2 desiliter = 0.2 liter
