I have one our part question left that I just don't understand! Please help me!!
Part 1 An 11.6 kg block of metal is suspended from a
scale and immersed in water as in the ﬁgure.
The dimensions of the block are 12.9 cm ×
9.7 cm × 9.7 cm. The 12.9 cm dimension is
vertical, and the top of the block is 5.07 cm
below the surface of the water.

What is the force exerted by the water on the top of the block? (Take P0 =
1.013 × 10
5
Pa .) The acceleration of gravity
is 9.8 m/s

Answer in units of N
Part 2
What is the force exerted by the water on the
bottom of the block?
Answer in units of N
Part 3
What is the reading of the spring scale?
Answer in units of N
Part 4
What is the buoyant force?
Answer in units of N

The force at any point is pressure*area
pressure=heightwater*densitywater*g
