Question
A cubical block of wood 10 cm on a side floats at the interface between oil and water with its lower surface horizontal and 4 cm below the interface. The density of oil is 
. The mass of block is
- 706 g
- 607 g
- 760 g
- 670 g
The correct answer is: 760 g
Weight of block
= Weight of displaced oil + Weight of displaced water
Þ 
Þ 
= 760 gm.
