Question 157837
well, {{{Density=Mass/Volume}}} ----> {{{rho=m/V}}}
Since the {{{rho}}} of wood is given = {{{430kg/m^3}}}, also the {{{V}}} of this wood, we'll use {{{Ratio}}} & {{{Proportion}}}:
{{{rho=430(kg)/1(m^3)=m/50(m^3)}}}, cross multiply;
{{{430(kg)*50(m^3)=m(m^3)}}}
{{{21500(kg)cross(m^3)/cross(m^3)=(m)cross(m^3)/cross(m^3)}}}
{{{m=21500kg}}} ----------------------> mass of {{{50m^3}}} wood
thank you,
