# A storage tank is

Answer :

When the cubical tank is full of water:

Volume of water = Volume of cube = 15.625 m^{3}

Then, Volume of cube = (length of edge of cube)^{3}

⇒ (length of edge of cube)^{3} = 16.625

⇒ length of edge of cube =

= 2.5 m

Now we know the length of the edge of the cube, i.e., 2.5 m.

When the present depth of the water is 1.3 m:

Depth = 1.3 m

Length of tank = 2.5 m

Breadth of tank = 2.5 m

So, volume of water upto depth 1.3 m = length × breadth × depth

= 2.5 × 2.5 × 1.3

= 8.125 m^{3}

Then, volume of water already used from the tank = (Volume of tank when it was full of water) – (Volume of water when depth is 1.3 m)

= 15.625 – 8.125

= 7.5 m^{3}

**Thus, volume of water already used from the tank is 7.5 m ^{3}.**
