This isn't quite exact, but 1/4 cup of butter (so a half stick if you're in the US) is 57 grams according to the conversion chart from allrecipes below. So use just a slightly heavy 1/4 cup or 1/2 stick. By the way, a 1/4 cup is 4 Tablespoons.

But since you asked for cubic feet...a standard US pallet is 40 inches by 48 inches. A standard semi-trailer height is around 110 inches, so you could possibly pile the stuff that tall as long as you did not overload the weight the pallet could support. Provided that the items did not really overlap or under-lap the pallet, you are looking at 40 inches plus 48 inches plus ---> now the height.
