The standard atmospheric pressure can not be expressed as:

Options

A. 760 mm Hg
B. 1.03 `Kg/(cm^2)`
C. 101.3 Kilopascal
D. 1.03 `(Kg)/(cm^3)`

Answer

To solve the question regarding the standard atmospheric pressure, we need to analyze the options provided and determine which one cannot be expressed as standard atmospheric pressure.

### Step-by-Step Solution:

1. **Understanding Standard Atmospheric Pressure**:
Standard atmospheric pressure is defined as the pressure exerted by the weight of air in the atmosphere at sea level. It is commonly expressed in various units such as mmHg, kPa, and kg/cm².

2. **Analyzing the Options**:
- **Option 1: 7060 mmHg**:
- This value can be converted to standard atmospheric pressure. Standard atmospheric pressure is approximately 760 mmHg. Therefore, this option is valid.

- **Option 2: 180 mmHg**:
- This is also a valid pressure measurement, although it is lower than standard atmospheric pressure. It can still be expressed in mmHg.

- **Option 3: 160 mmHg**:
- Similar to the previous options, this is a valid pressure measurement and can be expressed in mmHg.

- **Option 4: 1.03 kg/cm²**:
- This is a valid unit of pressure. To convert it to other units, we can use the conversion factor: 1 kg/cm² = 98.0665 kPa, which is also a valid expression of pressure.

- **Option 5: kg/cm³**:
- This unit is a measure of density (mass per unit volume), not pressure. Therefore, it cannot be used to express standard atmospheric pressure.

3. **Conclusion**:
After analyzing all the options, the one that cannot be expressed as standard atmospheric pressure is **kg/cm³**.

### Final Answer:
The standard atmospheric pressure cannot be expressed as: **kg/cm³**.
