Question

a water tank with 3cm thick wall is filled with 104000 litres of water. its length and breadth are 806 cm and 656 cm respectively. what is the hieght of the water in the tank​

Answer 1

The height of the water tank is 200 cm.

Given data :

Length of the tank = 806 cm

Breadth of the tank = 656 cm

Thickness of the tank = 3 cm

Water capacity = 104000 litres

So,

The length of the inner hollow space = (806-6) = 800 cm (3 cm thickness reduced from two sides)

The breadth of the inner hollow space = (656-6) = 650cm (3 cm thickness reduced from two sides)

Let,the height = x cm

Volume = (800×650× x) cm³

Water capacity = 104000 litres = 104000000 cm³

So,

800×650× x = 104000000

520x = 104000

52x = 10400

x = 200 cm (answer)
