The ratio of the densities of the two bodies is `3:4` and the ratio of specific heats is `4:3` Find the ratio of their thermal capacities for unit volume?

Explanation

To find the ratio of the thermal capacities for unit volume of two bodies given their densities and specific heats, we can follow these steps:

### Step-by-Step Solution:

1. **Define the Given Ratios**:
- Let the density of the first body be \( \rho_1 \) and the density of the second body be \( \rho_2 \).
- We are given the ratio of their densities:
\[
