$\bf \cfrac{volume}{volume}=\left(\cfrac{side}{side}\right)^3\quad thus\quad \cfrac{125}{27}=\left(\cfrac{h}{3}\right)^3\quad \textit{solve for }h$

jdoe0001 · Answer

notice, the sides must correspond for the ratio similarity
thus the numerator is the bigger one
whilst the denominator is the smaller one
