Answer:
1372 mL
Step-by-step explanation:
Since [tex]\frac{h_{1} }{h_{2} }=\frac{15}{21}=\frac{5}{7}[/tex]
then [tex]\frac{V_{1} }{V_{2} }= (\frac{5}{7})^{3}=\frac{125}{343}[/tex]
[tex]\frac{500}{v_{1} }=\frac{125}{343}[/tex]
[tex]125v_{2}=343[/tex] × [tex]500[/tex]
[tex]125v_{2}=171500[/tex]
[tex]v_{2}=1372mL[/tex]
