Hah, this reminds me of a joke I used to give my algebra I students:

If it takes 20 buckets of sand to make a sandcastle, how many buckets will it need to make another castle of the same shape,
but twice as big in each direction ?

Answer:

160 buckets. Since the large castle will be twice as long, twice as wideand twice as high, it will be 2 * 2 * 2 = 8 times the mass of the small one.

:rofl: :rofl: :lol: hahahaha woooo
