The diagram represents a rectangular block with mass $8.2\,\text{kg}$ submerged in sea water whose density is $1.10 \times 10^{3}\,\text{kg m}^{-3}$. What is the pressure difference between the block’s upper and lower surfaces?
- A$2.2 \times 10^{2}\,\text{Pa}$
- B$2.2 \times 10^{3}\,\text{Pa}$
- C$1.8 \times 10^{4}\,\text{Pa}$
- D$2.3 \times 10^{4}\,\text{Pa}$
