Question

If volume of the cubical tank is $2197000m^3$. Find the length of its side.

Answer 1

$\left(ii\right)$

volume of cubical tank $=2197000$ $m^3$

$\Rightarrow a^3=2197000$

$\Rightarrow a=\sqrt[3]{32197000}$

$\Rightarrow a=\sqrt[3]{313\times 13\times 13\times 10\times 10\times 10}$

$\Rightarrow a=13\times 10$

$\Rightarrow a=130m$

so , Length of its side is $130m$
