If 10 centimeter cube equals how many grams?

Answer 1

This question cannot be answered sensibly. A centimetre cube is a measure of volume, with dimensions [L3]. A gram is a measure of mass, with dimensions [M]. Basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. It takes only a little mental effort to compare a centimetre cube of air and a cm cube foot of lead to see that the two will have very different masses.

Answer 2

The mass of 10 cm^3 of a substance would depend on the density of that substance. To convert volume to mass, you need to know the density of the material in grams per cubic centimeter. You can then multiply the volume in cubic centimeters by the density to determine the mass in grams.
