Question
When a solid metal cube is completely submerged in a cylindrical vessel Containing milk with 30 cm diameter the level of milk rises by 
cm. Find the length of the edge of the metal cube.
Hint:
We use principle of Archimedes to find the length of the cube.
The correct answer is: The length of the edge of the cube is 10cm.
Explanations:
Step 1 of 1:
Let the length of the edge of the metal cube be a.
Volume of cube = a3
Given, r = 30/2 cm and h = 
By the principle of Archimedes,
Volume of risen milk = volume of cube
, discarding the negative value since distance cannot be negative.
Final Answer:
The length of the edge of the cube is 10cm.
