The container shown in the given image is completely filled with water. If the entire amount of water needs to be transferred into a cubical container, what should the side length of the cubical container be?

The correct option is A $15m$
Since the entire amount of water present in the container (shown in the given image) needs to be transferred to a cubical container, the capacity of both containers should be equal.

Volume of the given container = volume of the cubical container

The dimensions of the given container are: length,
$l=25m$, width, $w=5m,$ and height, $h=27m$.
Volume of the given container $=l\times w\times h=25\times 5\times 27=3375cum$

Let’s assume the length of the cubical container to be $s$ m.
Volume of the cubical container$=s^3$

$\Rightarrow s^3=3375$

$\Rightarrow s=\sqrt[3]{33375}=15m$
