Question

Average consumption of a milk of a family 3L . Express the value in SI unit

Answer 1

1 L=1 dm3
1dm3=1L=1000cm3
1L=1000cm3
3L=x
by cross multiplication
3(1000)=x
x=3000cm3
The SI unit is meter
1m=100cm
1m3=(100cm)^3
1m3=100×100×100cm3
1m3=1000000cm3
x =3000cm3
by cross multiplication
x(1000000)=(3000)(1)
x=3000/1000000
x=3/1000
x=0.003
3L in SI unit =0.003m3(volume)
