You don't say which units you want to change into cc's, so how can I give an answer?
100 units = 1 cc or 1 mL
you cannot change from units of area (in^2) to linear units (in). The question is impossible to answer
convert 1000 cc to ml
You need to find the conversion factor for the units in question.
It is 8,centimetres, exactly as in the question. A decimal representation does not imply a change in the measurement units.
How do you change metric units?
What should you do to change a value in SI units to a value in U.S. customary units?
No, the magnitude of a quantity does not change with a change in the system of units. The numerical value representing the quantity may change based on the system of units used, but the magnitude itself remains constant.
It looks like 3 cents - exactly as in the question! A decimal representation does not imply a change in the measurement units. If this is required then you need to specify the units into which the quantity is to be converted.
Yes, but not to the same question.
Your question contains the answer, 30 units by 46 units.
14 units up
Change is from 15 to 15 = 25 - 15 = 10 units. 10 units as a percentage of 15 units = 10/15*100 = 66.67 %
