I am sorry i don't know how to write the exponents of this problem. The problem is (1 x 10 to the 3rd power kg/in to the 3rd power) times (2 X 10 to the second power in to the 3rd power/gallon).
The answer is supposed to be 2 X 10 to the fifth power kg/gallon.
What happened to inches cubed? Any help would be greatly appreciated and I will gladly pay a membership so I can get some math help. Also any help in accessing math symbols would be a godsend!
