Different formulae are used for different shapes. For irregular shapes you may have to use integration, but since this is advanced math, you may first want to learn to use the formulae for different standard shapes.
liquids
because when the atoms meet up in the gases they separate and form more gases of matter. that's basically it!

they are volum,varaety,variation and visibility.
volum
Volum = length * width * height. Say your box is 1 m long, 1 m wide and 1 m high. The volum = 1m*1m*1m = 1m3
the quetion is wrong, are asking about length...or volum?
The volum is similar, the mass is different.
No, solids have a fixed volume that does not change easily. The particles in a solid are packed closely together, which gives them a fixed shape and volume. Changing the volume of a solid typically requires applying a significant amount of force or energy.
Reinforced Cement Concrete is called RCC.
