WorksheetFunction.SumSq (Excel)

Returns the sum of the squares of the arguments.

Arguments can either be numbers or names, arrays, or references that contain numbers. Numbers, logical values, and text representations of numbers that you type directly into the list of arguments are counted. If an argument is an array or reference, only numbers in that array or reference are counted. Empty cells, logical values, text, or error values in the array or reference are ignored. Arguments that are error values or text that cannot be translated into numbers cause errors.

SumSq (Arg1, Arg2, ..., Arg30)

Dim dblSumSq As Double
dblSumSq = WorksheetFunction.SumSq(Arg1:=)

Arguments

Arg1 - Number1, number2... - 1 to 30 arguments for which you want the sum of the squares. You can also use a single array or a reference to an array instead of arguments separated by commas
