Question 153128: I am the dad here and frustrated I can't help my son with this problem. It reads: If 1.0 km cubed of air has mass 1,200,000,000 kg, what is the density of air in g/cm cubed? The answer is given as 1.2x10 to the negative 3 g/cm cubed. We know the equation is density equals mass/volume but we obviously are missing something in the "power of" and the ending up with a negative power in the answer. I think we got the conversions correct, but am not even sure of that now. My son and I have worked on this (what appears to be a) simple math problem for over an hour and cannot explain the steps on getting to the answer given. I'm ashamed to admit we're both snowed. Any help would be appreciated. This is from a worksheet and I have no idea if it is from a textbook.

Question 155890: I am working on unit conversions for a nrsing test and used previous questions from your website. I was unaware that 1ft= 30.48 cm., so it took me a bit longer to solve the problem. 18.4 ft= 12in.= 2.54cm.= 1m. = 560.832m.
1 1ft. 1in. 100cm. 100
answer-5.61
I'm never sure which place value to round to. I'm uncertain
about setting up problems in terms of which unit goes on top/bottom. And with this particular problem, I knew that 12 inches=1 ft, but I initally tried using the the conversion 36 inches=3ft, which didn't work. How do you know which conversion factor to use? Thanks for your help! MW

Question 156235: I'm trying to help my son with a math problem and am drawing a blank. The problem says "Make up your own problem to calcuate the amount of money that you would spend on cigarettes if you started smoking in high school and continued until your death. You will need to make some assumptions about length of life. Assume 1 pack of cigarettes is $4.00." There is a conversion chart that shows 1 day equals 2 packages, I assume it is for this problem, 2 packs a day? Can you help, please?
