Who discovered how to determine buoyant force ?

Explanation

To determine who discovered how to calculate buoyant force, we can follow these steps:

### Step 1: Understand Buoyant Force
Buoyant force is the upward force exerted by a fluid on an object that is submerged in it. This force is equal to the weight of the fluid that is displaced by the object.

### Step 2: Identify the Formula
The buoyant force can be calculated using the formula:
\[ \text{Buoyant Force} = \text{Density of Liquid} \times \text{Volume Displaced} \times \text{Acceleration due to Gravity} \]
