A cuboidal tank is of length 12 m and breadth 8 m, if water is flowing from the pipe at the rate of 30m3/sec then find the level of water raised (in m) in the tank in 10 minutes.
Correct Answer : a ) 187.5Explanation :
According to the question
Let the height of water increased after 10 min = x m
Rate of flow of water = 30m3/sec
Volume of water filled in 10 minutes
⇒ 30 * 10 * 60 m3
We know that
Volume of cuboid = L * B * H
Where L, B and H are the length, breadth and height of the cuboid respectively.
Substituting the values
⇒ Volume = 12 * 8 * x
⇒ 12 * 8 * x = 30 * 10 * 60
⇒ x = 187.5 m
Hence, (a) is the correct answer.
