The density of a material in C.G.S. system is 8g/`cm^3` . In a system of units in which unit of length is 5 cm and unit of mass is 20g. What is the density of the material?

Explanation

To solve the problem, we need to convert the density of the material from the C.G.S. system to a new system of units where the unit of length is 5 cm and the unit of mass is 20 g.

### Step-by-Step Solution:

1. **Identify the given values:**
- Density in C.G.S. system: \( \rho = 8 \, \text{g/cm}^3 \)
- New unit of length: \( u_1 = 5 \, \text{cm} \)
- New unit of mass: \( u_2 = 20 \, \text{g} \)
