This 3D Distance Calculator helps you find the straight-line distance between two points in three-dimensional space. Enter the coordinates of both points, then apply the 3D distance formula by subtracting the corresponding x, y, and z values. After that, square each difference, add them together, and take the square root to get the final distance. It is a simple way to check answers, understand the formula clearly, and practise coordinate geometry step by step.

Step-by-step method

  1. Identify the two 3D points.
  2. Write the 3D distance formula.
  3. Substitute values and compute the distance.

Formula:

\(d = \sqrt{(x_{2} - x_{1})^{2} + (y_{2} - y_{1})^{2} + (z_{2} - z_{1})^{2}}\)
