Hej!
Odpowiedź:
wzór na objętość:
[tex]\Huge\boxed{V=\frac{m}{d} }[/tex]
5kg=5000g
920kg/m3 = 0,92g/cm3
Obliczenia:
[tex]\huge\boxed{V=\frac{5000g}{0,92\frac{g}{cm^{3} } } }\\\\\\\\\\\Huge\boxed{V=5435cm^{3}}[/tex]
[tex]dane:\\m = 5 \ kg\\d = 920\frac{kg}{m^{3}}\\szukane:\\V = ?\\\\d = \dfrac{m}{V} \ \ \rightarrow \ \ V = \dfrac{m}{d}\\\\V = \dfrac{5 \ kg}{920\frac{kg}{m^{3}}}\\\\\\\huge\boxed{V \approx0,005435 \ m^{3}\approx5,435 \ dm^{3}\approx 5 \ 435 \ cm^{3}}[/tex]
