Diketahui :

$rho_{raksa}=13,6,g/cm^3=13600,kg/m^3\ h_{cair}=14,cm=0,14,m\ h_{raksa}=2,cm=0,02,m$

Ditanya :

$rho_{cair}=?,kg/m^3$

Jawab :

$P_{raksa}=P_{cair}\\ rho_{raksa}times gtimes h_{raksa}=rho_{cair}times gtimes h_{cair}\\ rho_{raksa}times h_{raksa}=rho_{cair}times h_{cair}\\ rho_{cair}=frac{rho_{raksa}times h_{raksa}}{h_{cair}}\\ rho_{cair}=frac{13600,kg/m^3times0,02,m}{0,14,m}\\ rho_{cair}=1942,86,kg/m^3$
