The 5x5 grid as completed is given by:
76 37 58 19 40
25 61 22 43 79
64 10 46 82 28
13 49 70 31 67
52 73 34 55 16
The common sum = 230
Substituting the digits 9012345678 (in this order) for the corresponding letters, and allowing for due punctuation, we get: BLOCK UNITS.
For an explanation, refer to the solution submitted by Charlie in this location.
