It follows a very similar format to the pythagoras formula in 2D, in 3D it is: sqrt((x2-x1)^2 + (y2-y1)^2 + (z2-z1)^2)

Hi Madeline!
If your two points are (xโ, yโ, zโ) and (xโ, yโ, zโ), then the formula is:
Distance = โ[(xโโxโ)ยฒ + (yโโyโ)ยฒ + (zโโzโ)ยฒ]
For example, let's say you want to find the distance between the points (โ6, 4, โ15) and (2, โ5, โ3):
Distance = โ[(โ6โ2)ยฒ + (4โ(โ5))ยฒ + (โ15โ(โ3))ยฒ]
= โ[(โ8)ยฒ + (9)ยฒ + (โ12)ยฒ]
= โ[64 + 81 + 144]
= โ[289]
= 17
