Question

I need straight forward answers please

Answer 1

$we \: knw \: tht \\ \red{ \rho = \frac{mass}{volume} }$

$1000 = \frac{4}{ \green{v}}$

$v = \frac{4}{10 {}^{3} } \\ will \: be \: in \: m {}^{3}$

$1l = 10 {}^{ - 3}m {}^{3} \\ =1m {}^{3} = 10 {}^{3} l$

$v = \frac{4}{10 {}^{3} } \times 10 {}^{3} \\ \bold \ \orange{v = 4l}$
