Hello, curious reader! Ever wondered how far it is from your favorite pizza place to the moon? Or from the tip of your nose to your big toe? Well, we’ve got you covered with our 3D Distance Calculator! Let’s dive into the world of Pythagoras, but this time in 3D, and calculate those distances with a pinch of humor!
3D Distance Calculation Formula
The formula to calculate the distance between two points in a three-dimensional space is:
distance = sqrt((x2-x1)**2 + (y2-y1)**2 + (z2-z1)**2)

Limitations of 3D Distance Calculation
- Assumption of Euclidean space: Real-world distances might not follow this assumption due to the curvature of the Earth.
- Neglect of obstacles: The formula does not account for real-world obstacles between two points.
- Neglect of time: In some cases, especially in physics, time is also a factor in distance calculation.
