1 lb = 4 cups sifted . That is the equivlent given but I'm not sure how many cups are in a box, it might be different. I, also, don't buy powdered sugar in a box so I'm not sure, but I would think that measurment would work for your fudge.
THE AMERICAN'S CREED I believe in the United States of America as a government of the people, by the people, for the people, whose just powers are derived from the consent of the governed; a democracy in a Republic; a sovereign Nation of many sovereign States; a perfect Union one and inseparable, established upon those principles of freedom, equality, justice, and humanity for which American patriots scrificed their lives and fortunes. I therefore believe it is my duty to my country to love it, to suport its Constitution, to obey its laws, to respect it's flag, and to defend it against all enemies.

You will find websites vary on this one:
I like to use a lower amount than some websites state since making Icing etc one can always add more powdered sugar if needed but by adding too much initially you can get a dry product.
I find I often end up using 3 cups give or take 1/4 cup or so.~A
Sugar, brown 1 pound 2 1/4 c. firmly packed
Sugar, granulated 1 pound 2 1/4 c.
Sugar, powdered 1 pound 2 3/4 c.

Aliea, that sounds more like what is in a box to me. I hope the poster sees this. I'll try and keep it bumped for her.
