Question

water is drawn out of tank full to the brim .The shape of the tank is that of a cuboid of dimensions 3m×1.4m×80cm.if the rate of water flowing out is 100 cm^3 /s then find the height of the water level in the tank after 5 minutes​

Answer 1

Answer:

79.28 cm.

Step-by-step explanation:

The dimensions of the cuboid tank are given by 3m×1.4m×80cm or, 300cm×140cm×80cm, where the height of the tank is 80cm.

The tank was initially full of water and water is flowing out at a rate of 100cm³/Second.  

Let us assume that after 5 mins or, 300 seconds the height of water in the tank reduces by x cm.  

Then we can write, 300×140×(x)=100×300, ⇒ x=0.7142 cm.

Therefore the remaining height of water level in the tank after 5 mins. will be (80-0.7142) =79.28 cm. (Answer)
