$green{huge{a)}}$

$sf V_{mercury}=frac{8}{27}times V_{container}$

$sf frac{1}{3}~pi~r^2~h_{mercury}=frac{8}{27}times frac{1}{3}~pi~r^2~h_{container}$

$sf h_{mercury}=frac{8}{27}times h_{container}$ $sf =frac{8}{27}times 15$

$red{huge{sf h_{mercury}=frac{40}{9}~cm}}$

$\text{[math]}$

$green{huge{b)}}$

$sf V_{container}=frac{1}{3}times a_{container}times h_{container}$

$sf =frac{1}{3}times 45times 15$

$sf V_{container}=225~cm^3$

$sf V_{mercury}=frac{8}{27}times V_{container}$

$sf =frac{8}{27}times 225$

$sf V_{mercury}=frac{200}{3}~cm^3$

$sf V_{mercury}=frac{1}{3}times a_{mercury}times h_{mercury}$

$sf frac{1}{3}times a_{mercury}times frac{40}{9}=frac{200}{3}$

$sf a_{mercury}times frac{40}{27}=frac{200}{3}$

$sf a_{mercury}=frac{200}{3}div frac{40}{27}$

$sf a_{mercury}=frac{200}{3}times frac{27}{40}$

$red{huge{sf a_{mercury}=45~cm^2}}$

$\text{[math]}$

$green{huge{c)}}$

From $green{b)}$ , we got :

$red{huge{sf V_{container}=225~cm^3}}$
