Question

A cube of edge 8 cm is immersed completely in a vessel containing water. If the dimensions of the vessel 30
cm x 24 cm x 20 cm, find the rise of water level in the vessel.
​

Answer 1

Answer:

The volume of the cube is = (side) ^3 :….or

8^3 = 8*8*8 = 512 cubic centimeters. It means the amount of water displaced is 512 cubic cms

Now this volume of water is to be represented in a rectangular vessel having 20 cms length, 10 centimeters breadth, the height of water column is to find out :

The volume of the rectangular is = l * b * height, here is the working :

20 * 10 * height = 512 (equal to the displaced water), or

height = 512 / 200 = 2.56 centimeters

The rise of water level in the rectangular vessel is : 2.56 centimeters. is the answer.

Answer 2

Answer:

the rise of water level is 2.56 centimeters
