Answer:
Step-by-step explanation:
3D space  (x, y, z)  = (10, 45, 57)
I will use  x² + y² = (2D Hyp)²  and (2D Hyp)² + z² = (3D Hyp)²
which is just x² + y²  + z² = (3D Hyp)²
10² + 45²  + 57² = (3D Hyp)²
100 + 2025 + 3249    =  5374   =   (3D Hyp)²    the destance from the origin
                                                    =  73.31    the destance from the origin
