Answer: A cubical block of wood, 10.0 cm on a side, floats
Chapter 12, Problem 31E(choose chapter or problem)
A cubical block of wood, 10.0 cm on a side, floats at the interface between oil and water with its lower surface 1.50 cm below the interface (Fig. E12.31). The density of the oil is \(790 \mathrm{~kg} / \mathrm{m}^{3}\).
(a) What is the gauge pressure at the upper face of the block?
(b) What is the gauge pressure at the lower face of the block?
(c) What are the mass and density of the block?

QUESTION:
A cubical block of wood, 10.0 cm on a side, floats at the interface between oil and water with its lower surface 1.50 cm below the interface (Fig. E12.31). The density of the oil is \(790 \mathrm{~kg} / \mathrm{m}^{3}\).
(a) What is the gauge pressure at the upper face of the block?
(b) What is the gauge pressure at the lower face of the block?
(c) What are the mass and density of the block?
ANSWER:
Solution 31E
Step 1:
Introduction :
In this question, we have a wooden cube which is floating on the interface of oil and water
In the first part we need to find the gauge pressure on the upper part of the cube
In the second part we need to find the gauge pressure on the lower part of the cube
In the third part we need to find the mass and density of wood
Data given
Length of the cube
Length immersed in oil
Density of the oil
Let us consider the figure given
