Answer:
[tex]\sf \dfrac{b^9}{125}[/tex]
Step-by-step explanation:
We need to find out the volume of cube with the given side length . The side of the cube is ,
[tex]\sf\longrightarrow Side =\dfrac{1}{5}b^3[/tex]
Now as we know that the volume of cube is ,
[tex]\sf\longrightarrow Volume = side^3[/tex]
Substitute the given value ,
[tex]\sf\longrightarrow Volume =\Bigg(\dfrac{1}{5}b^3\Bigg)^3\\\\\sf\longrightarrow \boxed{\red{\sf Volume = \dfrac{b^9}{125}}}[/tex]
