Question

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

• A. $150$
• B. $140$
• C. $120$
• D. $100$

Answer 1

Answer: (D)

$100$

The dimensions of hall are $a=40m,b=25m,c=20m$

Then volume o thef hall is $V=a\times b\times c$

$V=40\times 25\times 20=20000cubicm$

Since, one box requires $200cubicm$

So, number of box required is $n=\frac{20000}{200}$

$\therefore n=100$ box
