a) 0,3m³=0,3*1m*1m*1m=0,3*1000mm*1000mm*1000mm=300000000mm³
b) 5cm³=5*1cm*1cm*1cm=5*10mm*10mm*10mm=5000mm³
c) 30dm³=30*1dm*1dm*1dm=30*100mm*100mm*100mm=30000000mm³

a) 0,00005m³
b) 1200mm³=1200*1mm*1mm*1mm=1200*0,001m*0,001m*0,001m=1200* 0,000000001m³=0,0000012m³
c) 3dm³=3*1dm*1dm*1dm=3*0,1m*0,1m*0,1m=3*0,001m³=0,003m³

a) 30kg/m³=30*1000g/1m*1m*1m=30*1000g/100*100*100=30*1000g/1000000cm³=30*0,001g/cm³=0,03g/cm³
resztę napisze w skrócie

b) 12dag/m³=12*100g/1000000cm³=12*0,0001g/cm³=0,0012g/cm³
6
a) 5kg/m³=5*1000g/1000dm³=5*1g/dm³=5g/dm³
b) 32g/cm³=32*1g/0,001cm³=32*1000g/dm³=32000g/dm³

polecam się na przyszłość
