A log of wood floats in water with `1/5` of its volume above the surface. What is the density of wood?

Explanation

To solve the problem of finding the density of the wooden log that floats in water with \( \frac{1}{5} \) of its volume above the surface, we can follow these steps:

### Step 1: Understand the Problem
We know that the log is floating, and \( \frac{1}{5} \) of its volume is above the water. This means that \( \frac{4}{5} \) of its volume is submerged in the water.

### Step 2: Define Variables
Let:
- \( V \) = Total volume of the wooden log
