Answer 2

Answer:

$\huge\boxed{a)\ 2,800cm^3=2.8l}\\\boxed{b)\ 12.4l=12,400cm^3}$

Step-by-step explanation:

$1l=1dm^3\\\\1dm=10cm\to1dm^3=(10cm)^3=1,000cm^3\\\\\text{therefore}\ 1l=1,000cm^3\to1cm^3=\dfrac{1}{1,000}l=0.001l\\\\a)\ 2,800cm^3=2,800\cdot0.001l=2.8l\\\\b)\ 12.4l=12.4\cdot1,000cm^3=12,400cm^3$
