How to remove this 2D array in C ++

Question

In a simple 1D array:

node *nodes =  new node[MAX_NODES];

Uninstall with:

delete [] nodes;

Deletes all nodes selected in the array.

But in this case:

float (*buildingArray)[3] = new float[10][3];

Is this operator the buildingArrayonly array of dimensions of 3 floating point pointers? And this is the line of liberation:

delete[] buildingArray;

Is the aforementioned release an deletearray, but I doubt if it will remove its links?
