Answer 1

Check below

Explanation:

1) These metric volume units can be easily converted by dividing or multiplying by 10 and its multiple. Like this: each step up on the ladder multiply by 10. Each step down divide by 10

`a)5270 \:cl=527\:dl\\b)kl=5.3 * 10=530 hl\\c)58000ml=5.8 dal =((58000)/(10000))\\d)0.39 dal=3.9 l\\e)7.8 dal=780 dl\\f)57.2 ml=5.72 cl`.

2) When it comes to area, the "ladder scheme" remains valid but now we'll multiply or divide by

`10^3`

Bear in mind these useful relations:

`1litre =(1)/(10^3)m^(3)`

`1 cm^(3) =1 ml`

`a) 3.7 l=3700 cm^(3)\\b)29.6 dm^(3)\\29.6 dm^(3) \rightarrow 29.6*10^(3) cm^3=29.6*10^(3) ml = 29.6*10^(2) cl \:or\:2960 cl\\c)8.1l=8100 cm^(3)\\d)5l=(5)/(10^(-3)) m^(3)\\e)5.2 cl=52ml=52 cm^(3)=52*10^(3)=52000 \:mm^(3)\\f)375 ml=375 cm^(3)\\g) 1300 cm^(3)=1300 ml=13 dl\\h) 8.6 ml= 8.6 cm^(3)*\: 10^(3)=8600 mm^(3)\\i) 51.8* 10^(11) l \rightarrow 51.8* 10^(-11)km^(3)`
