Energy density

Energy density. In physics, energy density is the amount of energy stored in a given system or region of space per unit volume. It is sometimes confused with energy per unit mass which is properly called specific energy or gravimetric energy density . Often only the useful or extractable energy is measured, which is to say that inaccessible ...

How to calculate storage space required | easyStorage

Volume is a measure how much space is occupied by an object. The basic volume calculation is length × width × height. It doesn''t matter which side you call what - the important thing is that all three are multiplied together. As an example: A box that is 20cm width, 15cm long and 10 cm height has a volume of: 20 × 15 × 10 = 3000 cm cubed.
