2.54 centimeter = 1 inch
(2.54)^3 = 1 cubic inch
16.387064
cc = 1 cubic inch
10,000 cc = how many cubic inches?
10,000 cc * 1 cubic inch / 16.387064 cc =
610.237 cubic inches
How many inches in 1 mile?
5,280 feet / mile * 12 inches /1 foot =
63,360
inches in a mile
(63,360)^3 =
254,358,061,056,000
Therefore, there are
2.54358 * 10^14 cubic inches in a cubic mile
(1 cubic mile / 2.54358 * 10^14 cubic inches) * 610.237 cubic inches =
2.39913 x 10^-12 cubic miles
I probably didn't use 9 unit multiples (because I don't know what that means), but the answer is correct.
