Question

The water tank with length $4$$m$ . breadth $1.5$$m$ and height $1$$m$ is completely filled with water. If it is to be emptied using a bucket of capacity $8$ litres, find how many times the bucket should be used to empty the tank completely?

• A. $75$
• B. $750$
• C. $300$
• D. $600$

Answer 1

The correct option is B $750$

Length of water tank = 4 m

Breadth of water tank = 1.5 m

Height of water tank = 1 m

Now,

Volume of tank = no. of buckets

Multiply volume of buckets

$4\times 1.5\times 1m^3=n.8l$

$6m^3=n.8$

$6000=n.8$

$n=\frac{6000}{8}$

$n=750$

$\therefore$ Total no. of buckets used = 750 /-

so, the answer is $B$
