What is the mass of the LEGO figurines being launched with spacecraft Juno?

How much additional fuel will be needed to get them to Jupiter?

With the following assumptions:

• Dimensions of a Lego figurine = ~0.59 cubic inches
• The figurines are composed of aluminum, which has a density of 0.098 pounds per cubic inch
• The payload weight of the rocket = ~18,000 pounds
• Launch price = ~$110 million The weight/mass of the figurines can be calculated as 0.05782 lbs or 26.23 grams: 0.59 cubic inches * 0.098 lbs/cubic inch = 0.05782 lbs  You can calculate the launch cost of the figurines to be roughly$1,060.

($110,000,000/18,000 lbs) * 0.05782 lbs * 3 figurines =$1,060


As for the fuel requirements, I could not locate a source for the amount of fuel required per pound, but it should be fairly easy to come up with the answer if you have that number.
