Explanation : Elements are the class of pure substances that cannot be physically separated; but they are made up of the same atoms of the same elements. When two or more elements are combined chemically with a chemical bond they become physically inseparable; which is called as a Molecule. Therefore, the term which represents represents a pure substance that can be separated chemically, but cannot be separated physically, that is made up of two or more different atoms is a molecule.
A compound is made up many different molecules. The main difference between the compound and the molecule is that a compound must have at least two different elements. So, it can be said that a compound is a type of molecule.
Mixtures are made up of different compounds which can be physically separated.
To find this, we can simply multiply all three dimensions to get the answer in cubic centimeters, and we get the answer above. If you want to be more specific, we can go by the sigfig rule and the answer would be rounded to 93 cm^3.
