Question

the inner length and breadth of an aquarium are 60 and 30 centimetres.it is half filled with water.when a stone is immersed in it the water level is rose by 10 centimetres.what is the volume of the stone?

Answer 1

Given that, the length and breadth of an aquarium are 60 and 30 centimeters.

Suppose, the aquarium is filled at height h

Now, according to the question:

The volume of the stone= volume of aquarium after stone is immersed- volume of aquarium before stone is immersed.

Thus,

The volume of the stone= 60*30*(h+10)-60*30*h=60*30*10=18000

Therefore, the volume of the stone is 18000 cm^3.

Answer 2

Step-by-step explanation:

volume of a rectangular box=length x breadth x heigth

stone immersed water level rose at=10

Volume of the stone =60 x 30 x 10

=18,000
