# How much time will it take to fill the water tank of 80 cm x 60 cm x 50 cm?

A water pump has a capacity to fill water at 10 liters per second. How much time will it take to fill the water tank of 80 cm x 60 cm x 50 cm?

(a) 12 Seconds

(b) 24 Seconds

(c) 36 Seconds

(D) 48 seconds

**Answer: (b) 24 Seconds**

**Solution:-**

The depth, width and length of a tank = 80 cm. 50 cm and 60 cm.

Then, the volume of the tank = 80 x 50 x 60

= 240,000 cm^3

As we know that, 1000 cm^3 = 1 lit

Therefore, 240,000 cm^3 = 240,000/1000

= 240 liters

A pump has a capacity to fill water at 10 liters/sec

Then, Time taken by pump to fill the tank = 240/10

= 24 sec.

Hence, the correct answer is option (b) 24 seconds.
