I have drawn a sketch of 3-D array to give a rough idea about how it looks like..it consists of many 2-D arrays also referred as Frames.

First see the no. of frames already crossed(given by the 1st dimension).. this means finding out how many elements of frames have already been covered. For that find (no. Of rows * no. Of columns)*no. Of frames given.

After reaching that particular frame, treat the sum as a simple 2-D array sum.

answer  is very simple to find the address of multidimension array 

like in above problem if you go from left to right direction then  we find the adress of element in row major order  and if you are go from right to left direction then you find the address of element in column mjor order 

A[lb1......ub1][lb2.......ub2][lb3.......up3] is given array then 

Adress of the A[l][m][n]=base adress +[(l-lb1)(ub2-lb2+1)(ub3-lb3+1)+(m-lb2)(ub3-lb3+1)+n-lb3]*w

put the value and find the answer,anwer will come in this case 628
