Answer 1

Answer:

The height of the water tank is 200 cm.

Step-by-step explanation:

The volume of water is given as 104,000 litres.

The length and breadth are given in cm, we convert cm into cubic cm.

We know that 1 litre =1000cm^3

So, the volume of water is = 104,000 * 1000cm^3

The water tank is a cuboid.

Formula of cuboid = length * breadth * height

We have the following values

V = 104,000 * 1000cm^3, length =800 cm and breadth = 650 cm.

Substitute the values in above.

Formula we get

104,000 * 1000 =800 * 650 * h

Rearrange the equation and solving for h

We get,

h = 104000 * 1000 / 800 * 650

h =104000 / 8 * 65

h = 13000/ 65

h = 1000/ 5

h = 200 cm

Therefore, the height of the water tank is 200 cm
