Explicație:

$l = 10cm \implies \: V_{cub} = l \times l \times l \implies \: V_{cub} = 1000{cm}^{3} \\ \\ \rho = 560kg/{m}^{3} = 0,56g/{cm}^{3} \\ \\ m = \rho \times V \implies \: m = 0,56g/{cm}^{3} \times 1000{cm}^{3} \implies \: m = 560g = 0,56kg \\ \\ G = m \times g \implies \: G = 0,56kg \times 9,8 N/kg \implies \: G = 5,488 \: N$
