Question

a cubodial
tank of dimension 8 m×5m ×3 m completely filled with water and outlet pipe can remove water from the tank at the rate of 20 litre per minute find the time taken in hours by pipe to completely empty the tank​

Answer 1

Answer:

∴ In 100 hr. pipe will completely empty the tank.

Step-by-step explanation:

Given:

Dimention of the cuboidal tank = 8 m x 5 m x 3 m.

Water flowing out from the pipe is 20 litre per minute.

To Find:

Time taken in hours by pipe to completely empty the tank.

Solution:

Volume of the cuboidal tank = (8 x 5 x 3) m³  

= 120 m³

∵ 1 m³ = 1000 litre.

∴ 120 m³ = 120 x 1000 litre

= 120000 litre

The pipe empty 20 litre in 1 minute

∴ In $\frac{120000}{20} minutes=\frac{120000}{20*60}hr=100hr$ pipe will completely empty the tank.

Answer 2

Step-by-step explanation:

∴ In 100 hr. pipe will completely empty the tank.

Step-by-step explanation:

Given:

Dimention of the cuboidal tank = 8 m x 5 m x 3 m.

Water flowing out from the pipe is 20 litre per minute.

To Find:

Time taken in hours by pipe to completely empty the tank.

Solution:

Volume of the cuboidal tank = (8 x 5 x 3) m³

= 120 m³

∵ 1 m³ = 1000 litre.

∴ 120 m³ = 120 x 1000 litre

= 120000 litre

The pipe empty 20 litre in 1 minute

∴ In \frac{120000}{20} minutes=\frac{120000}{20*60}hr=100hr

20

120000

minutes=

20∗60

120000

hr=100hr pipe will completely empty the tank.
