Examples
:
1) find the volume of a brick knowing that:
{ Length = 8Cm , width = 4Cm & height = 2Cm.}
2) Caculate the volume of a cuboid whose:
{length = 6 Cm , width = 3Cm , height = 2 Cm.}
Steps of Solving Problem in a scientific way:

************************************************** *****
Equal volumes of different substances have different masses:
Experiment :
1) get 2 cubes having the same volume (one of iron & the second of wood).
2) put iron cube in one pan of a common balance and the wooden cube in
The other pan.
Obs.:
Iron cube has higher mass than wooden cube.
Conc.:
Equal volumes of different substances have different masses.
