    3d Volume
In summary, the formula for calculating the volume of a 3D region in the 1st octant is V = ∫∫∫ dV, which represents the infinitesimal volume element. This calculation is significant as it allows us to determine the amount of space enclosed by a given region and can be applied in various fields such as engineering, physics, and chemistry. The limits of integration for this calculation can be determined by identifying the points of intersection between the region and each axis. It is possible to calculate the volume using only one integral by setting the appropriate bounds for the region along each axis. Additionally, the volume of a 3D region in the 1st octant cannot be negative as it represents a physical quantity
