Answer 1

Answer: 9 L

Step-by-step explanation:

Given

The dimension of the rectangular container is $40\times 30\times 25\ cm^3$

It is filled with $\frac{3}{5}$ of the height

Water present in the container

$\Rightarrow 40\times 30\times 25\times \dfrac{3}{5}\\\\\Rightarrow 18000\ cm^3$

Also, $1\ L=1000\ cm^3$

$\therefore 18,000\ cm^3=18\ L$

Now, half of the water is poured out

So, half is left

$\Rightarrow \dfrac{18}{2}=9\ L$

Thus, 9 L of water is left in the container
