One cubic centimeter equals how many cubic millimeters?
3.5 millimeters equals how many cubic centimeters?
How many ounces are in a cubic cm?
An ounce is a unit of mass. A cubic centimetre is a unit of capacity. The two units are therefore incompatible. However, if you are talking about fluid ounces (which are not the same as plain ounces), then there are 30 ml in one fluid ounce in the US. Therefore there are 0.0333 fluid ounces in a cubic cm (ml).

How many ounces are in a cm3?
There can be no equivalence. An ounce is a measure of mass. A cubic centimetre (cm^3) is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a cubic centimetre of air. How many ounces? Next consider a cubic centimetre of lead. How many ounces? The masses of equal volumes of the two substances will clearly be very different. So there is no direct conversion between mass and volume: you need to know the density of the substance to enable you to carry out the conversion.
