Cant really see it................
He is wrong.
The 10 inch cube is bigger than the 5 inch cube by 5 cm in EACH DIRECTION.
So, the 10 inch cube should be twice as big in volume by a factor of 2*2*2
=8
Okay let's see.
5 cm cube volume = 5*5*5 = 125 cc
10 cm cube volume = 10 * 10 * 10 = 1,000 cc
1,000 / 125 = 8
The anwser is 10,000 drops 1000 multiplied by 10 gives you the anwser
I don't have the ranges of numbers to see which range so clearly it's impossible to answer
