Question

A storage tank is in the form of cube when it is full of water the volume of the water is 15.6265 meter cube. if the present depth of the water is 1.3m then find the volume of water already used from tank.

Answer 1

Hi,

Let

the length of the storage tank = s m

Volume of the water in the tank =

Volume of the cube = s ^3 m^3

According to the problem,

s^3 = 15.625 m^3

s^3 = ( 2.5 )^3

s = 2.5 m

Present depth of the water = h1 = 1.3 m

Depth of the used water =h2 = s - h

= 2.5 - 1.3

h2 = 1.2 m

Therefore,

Volume of the used water

= length of the tank × length of the

breadth × depth of the used water

= s × s × h2

= 2.5 × 2.5 × 1.2

= 7.5 m^3

I hope this will useful to you.
