Question

ce volum are un corp de fier cu masa de 780 de grame?​

Answer 1

Răspuns:

$\bf\purple{V=9,9\:m^3}$

Explicație:

$\bf\red{\boxed{\rho=\frac{m}{V}}}$

$\rho_{Fe}=7,874\:\frac{g}{cm^3}=7874\:\frac{kg}{m^3}$

$m=780\:g=0,78\:kg$

$V=\frac{m}{\rho}=\frac{0,78\:kg}{7874\:\frac{kg}{m^3}}=\bf\purple{9,9\:m^3}$
