SUMMARY
The geometric centre of a body, also known as the centroid, is defined by the coordinates calculated through the integrals of the body's volume. The formulas for the x, y, and z coordinates are given by: \overline{x}= \frac{\int\int\int xdV}{\int\int\int dV}, \overline{y}= \frac{\int\int\int ydV}{\int\int\int dV}, and \overline{z}= \frac{\int\int\int zdV}{\int\int\int dV}. The denominator represents the total volume of the body. When considering constant density, the centroid coincides with the center of mass, as the density factor cancels out in the calculations.
