The dimensions of a hall are $$40 m, 25 m$$ and $$20 m$$. If the hall is to be filled by boxes of volume $$200\ cubic\ m$$, then the maximum number of box which can be accommodated in the hall is:


ANSWER

$$100$$


SOLUTION
The dimensions of hall are $$a=40m,b=25m,c=20m$$ 
Then volume o thef hall is $$V=a\times b\times c$$
$$V=40\times 25\times 20=20000\ cubic\ m$$
Since, one box requires $$200\ cubic\ m$$
So, number of box required is $$n=\dfrac{20000}{200}$$
$$\therefore n=100$$ box
