The volume of a shape 3m x 3m x 2m is 18m3.
The volume would be 18m3. 3x2x3 = 18
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
Maximum speed: Mach 0.96Operating speed: Mach 0.89

There are 1000000 cubic centimetres in one cubic metre. Therefore, 18 cubic metres is equal to 18 x 1000000 = 18000000 cubic centimetres.
Speeds faster than Mach 1 are measured in multiples of Mach, such as Mach 2 (twice the speed of sound), Mach 3 (three times), and so on. Each Mach number represents the speed of an object in relation to the speed of sound.
