A reservoir is in the form of a rectangular parallelepiped (cuboid). Its length is `20 mdot` If `18 k l` of water is removed from the reservoir, the water level goes down by `15 c mdot` Find the width of the reservoir `(1 k l=1 m^3)`

Explanation

Given:
The length of the cuboid reservoir is `20m`
`18kl` of water is removed from it the water level hoes down by `15cm`To Find:
The width of the reservoir
Solution:
It is given that when `18kl `water is removed from the reservoir the water level goes down by `15cm.`

Firstly, changing 15cm into m which will be `0.15m.`
Now let the width of the reservoir be `x`.
The volume of water removed from the reservoir `= 3x m^3`
Also,
the volume of the water removed from the reservoir `= 18kl`So,
`3x = 18`
to find the value of x we divide `18` by `3.`
`x = 18/3 m`
`x = 6m`
Therefore, the width of the reservoir is `6m`.
