Cubic centimetre (cc) which is equal to a millilitre, and a litre.
Volume = (length) x (width) x (height)
Two common units for mass are kilograms and grams
Density = Mass/Volume. Conversion between units will depend on what the two units are.
Liters and MilliLiters
When you say "English", I'm assuming you mean the "customary" system of units of measure that's used in two English speaking countries and a Burmese one. In that system, the volume units of cubic inch, cubic foot, and cubic yard are quite common. Also the cubic mile, though not so commonly heard.
Mass: Pound and Gram Volume: Gallon and Litre.

Cube one's volume = 9*9*9 = 729 cubic units. As there are two cubes, their volumes added together = 1458 cubic units.
Density = Mass/Volume. Conversion between units will depend on what the two units are.

While many different units can be used to measure volume, the most common units for measuring volume are the cubic centimeter (cm3) = 1 milliliter (ml).
direct measurement and displacement
Mass amount of matter in an object; given in units such as gramsVolume amount of space occupied by matter; milliliters (mL) and liters (L) are common units of volume
Surface area is two-dimensional. Volume has a third dimension: depth.
