Q7: Write a function called sumthesearrays, which takes a 3-dimensional array and returns the sum of all its elements. You can assume that the length, breadth, and height of 3D array is the same. So, it could be 2*2*2 array or 3*3*3 array and so on.(Hint: you need 3 loops) Do not import/use any external packages!!!! (i.e. numpy, math, etc.) [In python 3]

def sum_3d_array(three_dim_array): Returns the sum of a 3D array sum_3d_array(t0) 36 sum_3d_array(t1) 4 >sum_3d_array (t2) # YOUR CODE HERE
