Given:

Volume of cubical tank =
(1000)/(125) cubic meters.

To find:

The length of a side of the water tank.

Solution:

The volume of a cubical tank is:


V=a^3

Where, a is the side length.

It is given that the volume of cubical tank is
(1000)/(125) cubic meters. So,


a^3=(1000)/(125)


a^3=((10)^3)/(5^3)

Taking cube root on both sides, we get


a=(10)/(5)


a=2

Therefore, the length of a side of the water tank is 2 meters.
